Damn now i wish I would have became a chemist it looks like y'all do a lot of cool stuff
@@jeremydennard8362 costs tons to set up :/
@@BxnkrollBeatKillerBEATKMB my son wants to get into the snake venom extraction I bet its pricey as well to do
@@jeremydennard8362 yep. I would recommend less advanced stuff as a work up to reward (extraction you mentioned). It will capture interest in many aspects of chemistry and also allows you more time to afford advanced glassware. Stay well!
Please feel free to make hundreds of UA-cam videos about Nitrogen (or anything else for that matter) and do not worry about not telling us everything!
chem class for free ya'll
i believe same
I want him to tell us everything tho
@@briancooley8777 i see
Lol
I never want to hear the Professor say "The banana goes absolutely rigid" ever again...
Andrea Cordani Get your mind out of the gutter.

How do you think Viagra works?
...process of erection involves the release of nitric oxide (NO) in the corpus cavernosum as a result of sexual stimulation. NO activates the enzyme guanylate cyclase which results in increased levels of cyclic guanosine monophosphate (cGMP), leading to smooth muscle relaxation in blood vessels supplying the corpus cavernosum, resulting in increased blood flow and an erection.
Nitrogen!
The banana goes absolutely rigid
I once froze a single sugar coated wine gum in liquid nitrogen to see what would happen. It turned to a very brittle glass like material that shattered into very tiny bits when accidently dropped on the floor.. Unfortunately the tiny bits quickly turned back into very sticky sugar. This had spread finely across the whole of the lab floor, sticking everyone's shoes to the floor as they walked across it. Needless to say I was not very popular and had a lot of cleaning to do.
"When will people understand sometimes great advancements in science sometimes have uncomfortable repercussions? It's just a normal part of the scientific method!"
"Shut up and just grab a mop already!"
But you were able to do a wonderful demonstration of the properties of sodium stearate and/or ammonia.
Lukiel666 I just about understand why sodium stearate might be an ingredient of wine/fruit gums, but ammonia ?!!!
LOL Sodium stearate is soap. For washing the winegum residue off the floor. Ammonia also for cleaning.
Lukiel666 sodium stearate is also used as a food additive, which is why I was willing to believe it might be an ingredient in the process of making wine gums. I think we used sodium lauryl sulphate and water. As I recall the liquid nitrogen was intended to cool an ultra low vacuum diff pump, but I had been supplied with far more liquid nitrogen than was needed for my experiment.
Dr. Charles Goetz, my advisor as a chemistry major at Iowa State University, made the initial discovery that cream could be whipped when dissolved nitrogen at high pressure was released from the cream (circa 1930).
I am a retired chemist. Thank you for your videos.

Poliakoff:
"And it can make quite a spectacular mess...
...the sort that Neil hates."
Only after "the banana goes absolutely rigid."
@@f38stingray Well, if you fancy putting something at the temperature of liquid nitrogen up inside of you.
Speaking personally, whatever goes up inside me had better be nice and rigid *and at a temperature of 290-305 K*, or I will undergo a sudden exothermic reaction and thermal runaway, with much spatial redistribution of all objects in my reach.
Why quote the video, Do you assume we did not watch it ?
ProCactus Because it's correct to do so.

Neil is the most badass looking chemist I've ever seen.
Yes, chemistry in leather pants. $10 says he has a pair of assless chaps just like those.
You got that right. 😎
4:45 Man, those newfangled airbags. Can you imagine them putting those in every car in years to come? Progress is at hand!
Before you know it, they'll be forcing us to use seatbelts too!
As long as they don't force us to talk like the narrator in the "airbeg" video.
hopefully soon the idea of car accidents will be this laughable thing from the past when people were actually allowed to operate vehicles that move faster than our reflexes can handle, for hours at a time when our attention span lasts seconds.
Kairu Hakubi seconds? No
forgot to mention, some people have the delusion that their attention span lasts longer than that, not noticing the many little gaps and lapses. Those are the most dangerous of all.
Clearly we have attention spans longer than................now I forgot where I was going with that.
Those elemental series videos never get boring. Especially the new ones are great to watch!
My friend told me that his Mustang is running nitrous. I told him that my Volkswagen is producing nitrous.
I thought it was only nitric!
Volkswagen was pretty embarrassed by that whole scandal.
I wish this comment got the attention it deserves 😂
@@elephystry combustion engines produce a multitude of nitrogen oxides, commonly referred to as NOx
edit: clarity
My buddy runs on nitrous. Always walking around with balloons of it. Nice guy.
We need to discuss the elephant in the room...Neal's leather pants.
vlogerhood I was scrolling through the comments hoping nobody had mentioned it yet!
Rides a motorcycle.
vlogerhood some cool fact about nitrogen and demonstrations.. yet me too had to rewind when he walked down the hall and I was sure It wasn’t normal jeans. Then realizing he is also wearing motorcycle boots.. and the leather pants made more sense... although I wouldn’t be surprised if Neal was actually wearing a pair of leather pants ‘just because’. Haha
They are trousers.
Motorbike leathers
Always highly informative
Fascinating video as always!
On a sad point, has anyone else noticed how many funeral cards are collecting on the shelf? :(
Oliver73 - I do now....
Why did you make me notice that :(
The older you get, the more loved ones you will watch die. Maybe immortality isn't so great.
The Haber Process for making ammonia from Nitrogen is the most important reaction in industrial chemistry. Life would be so different if Fritz Haber didn't invent it.
Yes. We might have much more organic farming and a healthy soil biome, sequestering carbon in the soil, with a quite significant reduction in global warming.
@@red-baitingswine8816 but there would be much more people dying of starvation and famine.
@@cheesehead9555
.
Sources? (see Johnson, U of AZ, for data on increased yields with his methods - cover crops etc. He claims that this alone could stop or reverse accumulation of CO2 in the atmosphere/oceans! ).
@Lilith does stuff
.
Try using a dictionary. I have explained all this here.
@@red-baitingswine8816 Buddy, ammonia is used to prepare nearly every synthetic nitrogen compound we use. It goes beyond agriculture. Secondly, synthetic applications aren't bad except for when they're overused. You realize that we'd never be able to have fed the growing population with the methods you're describing? I'm an organic farmer.
Yay I absolutely LOVE seeing experiments on Periodic Videos!!!! Always makes my day to see Neil, Professor Poliakoff, and Brady at work!
How I wish my high school teachers taught chemistry like the Prof - he makes it so interesting!

Periodic Videos this was a nice video I'm glad I decided to watch it
NOx also contains nitrous oxide so it contains NO, N2O and NO2. Though not very much N2O but it's massively important as it has a global warming potential 300 times that of carbon dioxide and a half life of 150 years. My dissertation was on the catalysis of Nitrous Oxide. (6 years ago now. I miss chemistry.)
Have you done, or could you do, some videos on sections of the periodic table rather than just individual elements? The fascination of the periodic table itself is in the similarities among groups. So a video on Group11 would be as interesting as one on the alkali metals would be. Also a discussion of what transition metals are, etc.
Hello I am chandan. I have a question that how to make laughing gas.
Periodic Videos Hi there. What the NOS that people inject into petrol engines to make them run faster?
That man just made a mana potion!
Back in the 1970's my mother would wonder why ocasionally fresh cans of whipped cream would be dead. Turns out kids all around the US were getting a quick high from inhaling the N2O then returning the cans to the shelf. Manufacturers eventually put shrink wrap on the caps to reveal tampered cans to shoppers.
Whippets! 😂
My favorite thing about nitrogen is, that pretty much all explosives we use, have nitro groups in them. And I love explosions and also fireworks.
☕️ Love morning lessons
What I learned today:
You can shatter practically any object no matter how flexible it is by first putting it in liquid nitrogen
Professor, greetings from America. You've inspired the young scientific boy in me time and time again. You're a treasure to your nation and the world. Thank you for all of the videos and all of the years!!!
These videos are just amazing.
And highly addictive.
Congratulations!!!
Yay, updated videos! Amazing production, Brady.
Could you do videos on F block elements in general? That would be great
ya it's interesting how much their chemistry overlaps (at least for the lanthanides)
Tallie Lintra I'd like to see a video on the element of music, as described on the totally not satirical, educational program Look Around You.
Look Around You is amazing
not so for the lanthanides... but yes most of the actinides are under very heavy restrictions (plenty of labs make Uranium compounds, but the paperwork and delay is tedious if it's not your specific area of interest).
I personally have used all the lanthanides except the radioactive one (Promethium). Their chemistry is also very similar to Yttrium.
However, lanthanides vary considerably in magnetic and electronic properties so they are quite interesting not to study individually but in series since they produce mostly isostructural compounds
Well if you haven't got the time to watch all of the videos and you need easy answers you can start at Uranium and just go from there. There's a bit of physics in that one as far as i can recall.
Excelente video.... Gracias por los aportes demostrativos de la química a toda la comunidad. Continúen haciendo más Periodic Videos...
I make bad science puns, but only periodically.
🤣
I’ve been waiting for this video so long! (Nitrogen is one of my favourite elements)
Hope you liked it
I did! I can’t wait for the next video!
It's always the tie. Love it
Once again MANY THANKS to the professor, Neal and the team... Best invested 12 minutes of the week.
5:12 Those shoes are awesome! Neil style score: 100/10
Thank you! I've always wanted to see the reaction between NO and O2.
For the petrol/diesel engines, you should have mentioned the catalytic converters. I've always found them really intresting, and I would love a more in-depth explaination of the adsorption mechanisms on platinum and palladium.
I had my last A level chemistry exam today. I just want to say how grateful I am for these videos. They're all so interesting and really helped me to appreciate the stuff I learnt in lessons. Depending on where I end up at uni I may not study chemistry again. It is a wonderful subject and these videos have helped me realise that. Thanks for making them!
Gotta love those electrophiles ay?
And how are you, where did you end up?
Wow, congratulations! Is chemistry absent from your life now?
What are you up to now? Just curious.
I'd recommend showing the hammer smashing banana bit, to anyone on a dating site that sends you unsolicited fruit pics.
He should do it again but with an eggplant this time.
One of the best channels!! Thank you so much!
This is just a brilliant video. Packed full of interesting information and fascinating experiments and so well shot as well.
As a learning chemistry student, I love these elements videos, so interesting
I have an Inorganic Chemistry exam in a couple of hours, and Nitrogen is one of the main elements I had to study. This video is awesome really
Neil's boots are wicked. The Stig always dominates.
So cool for something we breath everyday.
alexander williams I'm not sure...
Including the NOx
Another wonderfully informative video by our very own Processor Proton, keep up the sterling work
Always good to see a new video, they are few and far between these days.
Poliakoff for president of the world!
Great mix of experiments.
The word you you were looking for when talking about NOx regarding diesel engines is their higher compression ratio thus higher temperatures.
Plus I believe a large factor in the production of NOx is because a diesel engine normally runs very lean, the cylinder always had an excess of oxygen that doesn't get burnt, and that can combine with nitrogen.
@Curtis You are right, and @logan thompson is only partially right. Diesel engines actually have lower combustion and exhaust temperatures than gasoline engines, but the fact that there is always excess oxygen is the main contributing factor for them to have higher emissions of nitrogen oxides.
That still leave the diesel engines particulates as part of the exhaust when they start rolling coal.
That's a really long word.
Thank you sir
You helped me to remember most of my inorganic reactions
I love these videos too much! Thank you!!
I love your chemistry video, they are fun and curious
Published 3 hours ago - 1300 thumbs up! - It simply means You have a quite a big audience. Love Your's videos! Can't wait for more.
Thanks we can’t wait to make more.
Professor. Your videos are fantastic. They are very interesting and easy to understand.
Congratulations from Brasil!
This is probably the most interesting video y'all've put out!
Thanks. Hope you shared it with some friends. :)
Great episode! Nice that you ended it with the NOx problem on diesel engines... You could also explain how urea cleans these NOx on modern after treatment systems.
Neil is clearly a very serious guy - never appears to smile. I guess he's too busy making sure the Professor doesn't hurt himself!
Thumbs up to everyone watching this video.
y’all could be watching k pop or cat videos, but y’all sticking to science and educational videos. Y’all are the real ones!
Top notch stuff as always. Keep 'em coming.
We’ll try.
Petrol/gasoline engines do make NOx. The lower the compression ratio, the less conversion occurs in general. Diesel engines tend to run higher compression than gasoline/petrol which contributes, as does the general over abundance of air in a diesel engine, to high NOx production.
I love the videos- thank you so much to the whole team for doing what you do!
Awesome as always! Thank you Professor 🤔
The Professor is 'THE MAN."
As a biologist, we would use melting solid N2 to freeze samples. We would pour liquid nitrogen into a dewar, then place it in a vacuum chamber with a plexiglas lid, and pump the air out. The nitrogen would boil viciously until only only the slowest molecules remain, and they would solidify to a slurry. Then we would let air back in rapidly, remove the lid, and you would have a few seconds while the nitrogen was melting to put your sample in. The freezing nitrogen is quite beautiful, it forms like spaghetti ice, litlle growing worms of ice, each wit a droplet at the top.
The reason we used it rather than liquid nitrogen is that not only is it a couple degrees colder (-212°), it also stays liquid until all the solid is molten, meaning your sample is less prone to the Leidenfrost effect, and you get much more rapid cooling, leading to partial vitrification of the sample which you need to study undisrupted cellular structures.
Have you guys ever made a video on glass? Something so fragile, yet so resistant; the main material in any chemical lab. I would love to know a little bit more about it.
7:15
I think that's a bit wrong? Nitrogen has 7, oxygen has 8. Or 5 and 6 in the outer shell.
Indeed, oxygen has 6 valence electrons not total electrons. It has 8 electrons in total.
I can't figure out what logic could possibly result in that statement. I definitely can't figure out how it got past any editor during post-production.
Yes, he meant the total electrons for nitrogen and the valence electrons for oxygen. It can get a little confusing sometimes.
he meant Valens electron
This was really good. Thanks.
Absolutely Amazing!!!!
Awesome videos!
If I only had watched these videos back in my first semester...
Nice video! Some time ago I made a video some time ago about magnesium and nitrogen reacting to form magnesium nitride. :)
Hello! I'm Chunying's child and I love your videos.I also subscribed to your channel.
This was an unexpectedly pleasant video. I really loved 9:52 and 10:55. I can't explain why but those two scenes made me smile a lot.
5:40 that is a very cute action figure you got there, where can I buy one?
Thats just a playmobil figure.
7:21 Just to remind that nitrogen has a total of 7 electrons, but has 5 at the outermost shell; oxygen has a total of 8 electrons and 6 at the outermost shell. The professor had a mistake saying that nitrogen has 7 electrons and oxygen has 6, but didn’t note that the conditions are different!
Dear Periodic Videos team, thank you very much for every video released...
You’re welcome.
Really informative and packed with experiments!!! Excellent video!!!It would have been interesting to show that nitrous oxide is the only other gas besides oxygen that relights a glowing splint. One of the reasons it's used as a liquid oxidiser in racing cars (Drag racing)

Hi Professor, thanks for your autograph:) regards Mark!
Best professor on universe
This is a science treasure of all the world!
Your the best professor
This was the quality video I subscribed for
Thank you for being a subscriber. Hope you’re a bell subscriber. It’s getting harder and harder to reach even our subscribers these days!
Great video.
That's AMAZING!
Beautiful video :)
Thank you for the clarification about the remaining N2O in spray cream. Spared me a lengthy experiment :P
You should make an hour long video on ALL The elements to educate us more!
Another excellent video! One thing to point out however, petrol/gasoline engines DO make NOx - it's just easier on petrol engines to make them emit less NOx, using either EGR (Exhaust Gas Recirculation) or adjusting cam timing to keep combustion temperatures down. Diesel engines can't really operate without those high temperatures however, so to deal with the NOx we are saddled with DEF (diesel exhaust fluid) systems in the US, which makes diesel engines, normally dependable, into cantankerous beasts with fierce maintenance requirements.
Useful for sparging for anaerobic work
thanks professor woww
Great professor
9:58 So that's why the blood of Horseshoe Crabs is blue, due to the copper. Excellent video Professor!
I have to say, I know about fume hoods of course, but seeing it at work at 5:10 is really impressive.
Nice to see Neil is going through his industrial goth phase.
Nevertheless, *organic* nitrogen is the by far most important form of nitrogen.
"It's really quite beautiful when you heat it up."
(sample suddenly bursts into sparking flames)
I love this channel.
Thank you
Very interesting and nicely produced video.
thank you
You can also very easily generate NO2 by the reaction of concentrated nitric acid with ethanol. I once made the mistake of rinsing through a frit with ethanol then nitric acid, and learned my lesson quite quickly.
This is a nice video
At the risk of revealing too much about myself, my favourite application for nitrogen is synthesising azidoazide azide. This compound is so unstable, it is actually beyond our capabilities of measurement. If you want to know more about it, I recommend SciShow's video on the 5 most dangerous chemicals.
I read Derek's piece on this. Apparently you have to keep it in an autoclave for a week at a time, take it out to do something with it -- very, very carefully -- and put it back in for another week. Rinse and repeat for months. And then, when it's time to characterise your sample, as like as not you'll blow up three rotavaps before you can even get a sample as far as the spectrometer, and probably blow that up as well.
There's crazy ... and then there's Klapötke crazy. (Though honestly, if I had my life to live over again, I'd go into chemistry and sign on with his group. You couldn't call it a boring life, really.)
Love the videos... is anyone else curious about that hitman Neil
They call him "Neil" because his real name is Igor. :)
A great great scientist
Thank you!
