- Atoms, elements, molecules... What's the difference? This is part 3 in the Stated Clearly series: An Introduction to Chemistry. In it you will find a simplified definition of a molecule, you will learn how we model molecules, and you will see actual images of real molecules and their vibrational modes!

MORE ON OUR DEFINITION OF A MOLECULE
In this video we describe a molecule as "a group of atoms stuck together, usually through chemical bonds"
This definition is great because it's so easy to make sense of, but there are some problems with it. Biologists will sometimes consider a double stranded chain of DNA to be a "single molecule", even though each half of the strand is bound to the other via non-chemical hydrogen bonds. The same is true for some protein complexes composed of multiple sub-units.
Alternatively, some crystals (such as quartz) are made of repeating patterns of atoms all chemically bound. Using our definition, you'd have to consider an entire quartz crystal to be a "single molecule". Chemists don't usually do this, instead they consider each repeating sub-unit to be a molecule. Pure metals have a similar issue.
Language is a living, evolving mess! Even in formal scientific fields where you might expect more consistency.
MORE ON HYDROGEN MOLECULE FORMATION
In this animation we show a hydrogen molecule forming in space via a collision of just two atoms. Normally, this reaction also requires some sort of dust or ice particle to trap atoms as they bind together.
To avoid distraction when teaching the basic concept of a molecule, we chose to ignore this technicality in the animation. You can read here about how hydrogen molecules normally form in space: www.sciencedir...

I'm 40 years old, and I hated chemistry when I was in high school. Lately, I've started to get curious about basic science. I'm so glad I came across your videos. They're so clear, interesting, and exciting. The world of science is crazy. Thank you!
These animations must take eons to make! As someone who has played around with really simple ones, I can truly appreciate the kind of effort you put into them.
Or did you mean, "Ions to make"? Hehe
@@TiddlyBlinx ouch! that joke is _beyond redemption_
Lol
😂@@TiddlyBlinx
I'm almost 40 and untill today I never really understood what a molecule is (althought I completed school, university, etc). And now I do, thanks to be feeling humble and for this awesome video. Seing an actual real molecule was just beautiful. Thank you man (and your team)!
nig--- u should be here u should be workin ur 9 to 5 job
This has to be the MOST underrated channel on yt.
it is,
AGREE!
This and The Science Asylum
Indeed.
for sure
Can this channel please get more attention? Jeez.
Correction. Geez*
@@willhart3850 Wow thank you I can't believe this mistake went unattended to for 3 years you're a hero :)
@@poketopa1234 jeez sound better tho
@@poketopa1234hi after 4years lol
Thanks I was always confused between atoms and molecules and their difference. Brilliant video 👌 as always.
I think it's safe to say;
that was *Stated Clearly*
No stop your not funny sorry to break it to ya😒😒😒😒😒
No
Mate that ain’t funny,it’s just REALLY cringey
Funny
I laughed
It's funny but not everyone will understand it, like the three who wrote that.
I never understood this as a child, and I never understood it while in high school as a teenager either.
I've never had to use this information for anything but I'm glad I've finally understood it as an adult - thanks!
Same here.
I still can't understand
????
Same but i still can't understand
this channel is too underrated. it deserves to be as famous as bright side or smth. you nice, keep going.
That was so much more than "what is a molecule?". Your title is... Clearly Understated
Great job Jon, as always.
OMG you've made chemistry 'bearable'! I wish I had these videos when I was in school. Super helpful and "Stated Clearly"!
My kids are gonna be so excited when they wake up, we love your content delivery. An we get a "why birds are dinosaurs" video?
I'm always using your videos on my friends. Lol
Have a great day Jon. Peace. Peace.
I dont learn this in school but i want to learn about molecules. Thanks for the video! Really helped me understand!
Ogi Drapic Sameee
your channel along with similar other channels are what make youtube interesting
Keep up the great work
it's amazing how a nearly 200year old theory is so accurate when confirmed with technology.
I LOVE LOVE LOVE the way the argon and hydrogen c02 bond together conveniently
1:39 - An Iconic phrase from the Iconic novel, A Christmas Carol.
I am from India 🇮🇳, watching your videos with my friends. AWESOME
Thank you for the video. I am grateful for your time and contribution. Kind regards, Akira.
trying to home school a reluctant student - I would love to see more videos on Chemistry (currently blowing my teenager's mind)...you are so good at making it make sense, these have been a god send!
The quality, clarity and depth are always amazing. Thank you
I never clicked so fast when I saw this new video ❤️ More!! We need more!!
Beautiful story Jon. Science is as accurate as it can be! Great work!
I never knew that it was possible to scan a molecule, nor its bonds. What an amazing thing to know.
You think that's impressive? I saw recently that someone had managed to take a photograph of an atom. Required a bit of trickery to do it; changing the wavelength of the laser used to be able to get the right resolution and then changing the wavelength back to see the resulting image, but it's still a photograph.
Or at least, that's my understanding of the process involved. It's a bit over my head.
@@EdwardHowton seems awesome. I'll look into that.
How do you have only 1/2MM subscribers? You guys are fantastic. Many, many thanks.
*You are one of the Best Science Based Education Channel and I appreciate ur Hard work as u try to get people interested in Science*
*Thank u*
"For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring." -Saint Carl Sagan
Jesus Christ, that's good!
Ironic coming from you.
How the fuck did you get the verified tag on your name?
Carl Sagan was no saint. He was a plagiarizer who took credit for discoveries of other scientists. Apparently he could get away with it. The only reason he became rich and famous was jumping on the media bandwagon and becoming a tv show host. Same story with the so called Genius Albert Einstein who practiced intellectual property theft while he was working in the patent office and he also had his wife do all his math for him.
@Roderick Stoutamire and neither are you
This youtube channel has single handedly taught me more about chemistry than 12 years in the public school system
Excellent video ❤👌
This channel is pure gold.
Non of you may see it, but this video is AWESOME!!!
Love your vids man. Thank you so much for showing and teaching me so much about science in your clear and straightforward fashion. A big thank you from me these vids really helped.
How I wish my Chemistry class way back 10 yrs ago explain atoms behaviour like these so I won't need to retake the subject 3 times to pass the subject.
I love how the complex behaviour of atom simplified so an ordinary person knows the basic overview of an atom before memorizing table of elements and solving stoichiometry. :(
Yes same here... I would understand it much better if such videos were available 29 years back for me
very well rounded video with real world application examples. thanks so much
This is probably the only video on this subject that I actually understand and learned something from.
This videos and the others I have seen from this channel are simply amazing, thank you so SO much
youre never too old to learn,im 60 n just wish we had youtube when i was a kid.
It blows my mind that there are tiny crystals inside watches with electronics attached to count the vibrations of their molecules, so that a watch hand can move at an exact time. That honestly sounds like magic to me, and until now i never understood why some of my science friends would loosely compare science to magic, and be so fascinated in seemingly mundane things like the bubbles in a glass of water. I wont lie i have always been interested but the pure scale of these things has been hard to wrap my head around!
Nice.
Photons and spectroscopy helped open this world, maybe something about energy transfer as you noted in passing, and frequency relations to electron orbitals.
Folks love frequencies
An atom (or an ion at this point) goes to a bar and says: "Last night I think I lost an electron." "are you sure?", "I am positive".
You mean (or cat ion at this point)
Hahaha
Well, and then a _neutron_ comes in after that and orders a Vodka Martini. When asking how much it owes, the bartender smiles and says:
"For _you,_ my friend... *free of charge."*
@Abdullah Al-Farra Actually, I stole this one from Sheldon Cooper...
🤣🤓🤣🤣🤣✌️
This has to be the MOST underrated channel on yt
Wow It's incredible, I'm started to study chemistry on my own, and I love to learn watching videos on youtube, I was looking for one about molecules and bum just today someone has made and awesome video, thanks so much!
I just found your channel and i'll watch EVERY SINGLE ONE of your videos, they are amazing.
this is the greatest channel yet! thanks for making these great contents! Please keep up the good work
Wow! I love how you included the applications of these molecular properties. Everything's so clear now.
You're smart as for: You know everything about science and memorize what to say! I'm sorry I'm late.
I still love this channel no matter what happens in my exams! I get an A-, sometimes A+ Because of this channel! Thanks Jon! I'll be sharing this video! :D
Compelling the tape was epic proportions of atoms (held) together to create 2, 3 and millions of molecules.
Great video! Congratulations for mentioning our great universal teacher Carl Sagan!
Of course so excited I'm learning from this channel but one thing that gets me more pumped is the intro beat! I mean! 💥💥💥💥💥💥💥💥💥
I am a visual learner ! This video has helped me LOADS ! Thank you !
this helped me so much in understanding the difference between atoms and molecules. THX!!!!!!
THIS WAS SO HELPFUL, THAT YOU ALL!!!
We need more of this make this a series 😢
This video has more info than I needed .......... but ok, I guess . At least it gave me what I couldn't find anywhere.
If there are more in this series, it might be useful to mention somewhere that ionic bonds don't really form molecules because you don't, for example, have a single Na bonded to a Cl.
I never learned this through two engineering degrees, and had a materials scientist explain it to me over lunch one day. It seemed so fundamental that somebody should have mentioned it explicitly at some point.
Well, as we ordinarily meet them, that's true. But when vaporized, there *are* actual, separate molecules of NaCl.
That said, this example is one of the strongest of ionic bonds; I'm sure there are many other species that would dissociate before reaching their boiling points.
Fred
Real good narration on a very complex topic, thank you for that
AMAZING VIDEO ,,, 🎉❤❤ 👏👏 STATED CLEARLY ,,,MADE EASY FOR ME.
I learned this in university over two weeks. I learned it here in 4min (first half of the video) and learned it better.
YAY!!! New Stated Clearly video!!! ❤❤❤
Just found your channel man, absolutely love it
5:36 you and me*
that's the level of nitpicking I can come up with. Awesome video!
bro- I couldnt understand this in a 60 min lecture u made it all so easy in like 10 mins 🥲 thx
Wow!! This is just perfect! Thank you
Teachers: lebfsohhskfjankab
Stated clearly: is stated very clearly
Underrated comment
That image of pentacene was really cool!
You deserve a million+ subs.
Teacher here....I love this channel
High school organic chemistry class all over again. :-) Well, it's nice to have a review every 57 years or so.
I understand what a molecule is now. Thanks!
Please make more videos like this, on the physics side such as molecules and atoms.
Who is here cause of exam
🙋🏾♀️😭😭
You
Me
Mee
You and Me.
Please make a video on how organic molecules came about!
TOP presentation. One of the best video I have seen. Thank you
Thanks.Really helpful.
A lot of information in short.
It is indeed Stated Clearly! Thank you so much for the video!
Much better than crash course. A quality.
thank you this helped us understand molecules more
Thank you my friend. 🙏💯👍
So am I accurate in saying that a molecule cannot consist of a single atom? Two or more are needed to qualify? (Though the two can be of the same *type* of atom, e.g. a molecule of H2 having 2 hydrogen atoms.)
Yep.
This is the type of channel i always certainly subscribe to, and 'ring' the bell.
yo thanks for uploading this video its very useful and it is STATED CLEARLY!!!!!
3:58 A perpetual tug of war between two forces? Sounds a lot like "free energy"!
You are right about stated clearly. I understand!
love ur definition of molecules my g!!
This video was awesome
Truly Loved it
Wow, this actually helped a lot!
This channel is amazing
Love your videos!!!
My kids 3 and 5 love that atomic game too
Thank you for a well explained video
Amazing and stated clearly
indeed! it is stated clearly. wonderfully crafted!
Say, at 0m18s and also 2m12s, I thought that fatty acid might be stearic acid, but I see (Wikipedia) that stearic acid is C₁₇H₃₅COOH; the one shown here is C₁₁H₂₃COOH.
Wikipedia also says this one is called lauric acid. (I have to look these things up, not being terribly conversant in organic chemistry.)
≈4½min: It's not just vibrations, it's also rotations.
The lowest vibration energy level (for small gas molecules) is usually accessible only way above room temp; rotation energy levels are easily reached at room temp.
(Both kinds are quantized.)
Hey, this is a very nice, informative presentation. I wish I were a teacher, cause I *would* be using this - it's short and well explained!
Fred
I am an indian.I used to watch ur videos. How nice ur videos and such a great person u are.
One of the Best Channel. 👍👍👍
Thanks for the video. :)
woww! i really can understand the concept well great job
Amazing as always :)
Excellent summary! Thanks.
Excellent channel! Your work would be an asset in the classroom... If I would've seen a video like this when I was in highschool thing's would've made sense to me, and I would've probably wanted to learn more about it.
Good job
