- Why is the periodic table arranged the way it is? There are specific reasons, you know. Because of the way we organize the elements, there are special patterns that emerge. And you know how Professor Dave feels about patterns. He likes them.

when you have a chem midterm tomorrow so you pray to god for help and he sends you a link to jesus
amen!
I want to like this comment more than once lol
When you need a 60+ on the final to pass chemistry, allows rely on Jesus
Jada Lowery I’m no where near my mid term this is homework and I got lucky. Now I don’t need this unit. Thanks Science Jesus!
Bruh preach . my midterm tmr
I was here in grade 11, I'm back here in first year uni.
Thanks a lot, still
What are you studying?
Same !!
I wanna be a computer engineer ffs, why do I need chem smh..
@@nyankrunex9654 hahaha, r u serious? how do you think computers work? You need chemistry more than literally any other science
No stress But two Chem courses don’t look good
Guy on youtube: has beard and long hair
Everybody: JESUSJESUSJESUS
Stfu it's actually funny
Jesus sus

I just want to say thank you! My entire study group has been trying to interpret our professor for weeks now, our test was two days ago, and we learned our entire unit from your videos. We all got A's. We were all sitting around the tv watching your videos as everything just completely fell into place. We must have said, "Oh my god, it's so simple though!" every 3 minutes. Thank you so much! People don't hear that enough, so just to let you know, you are well appreciated.
3 hours of reading dry book and taking notes or...8 mins of concise teaching, thank you.
6 years ago but no replies-- I don't think my algebra classes are working, that must be impossible-
ahhhhhhhhhhhhhh
@@CocoLoco878
Exactly
Thank you, you explained it so much better than my teacher.
thank you teacher for you helping
that's true

VelstryoxDP I have to look this up for homework. This is why school isn’t actually important and doesn’t need this much funding.
same hahahaha
It is the hit before my big test and I’m studying and the same guy that helped me pass calculus last semester has chemistry tutorials as well! The profound genius that is professor Dave is unmatched.
How’d your test go?
thanks for asking. I got a B in the class. i did good enough on the final to get a B in the class. I graduated with my associates degree with high honors. I had straight As until I took this chemistry course (I had never taken a chemistry course in my whole entire life yet i thought i should take a level 2 chemistry course like an idiot) so I was about to get a full scholarship to governors state university and i just graduated this may in computer science. I also was able to get a job right after my associate degree with a software development company. had i not had your videos my gpa would have been less than 3.8 and i wouldn't have got my full scholarship that lead to my bachelors.
@@JimmyGeniusEllis That's wonderful to hear that you got your scholarship, degree and job! Just to be clear, I'm not Professor Dave; I just like to check in with people who left comments long ago. I think it drives up engagement on videos, and it has also lead to some cool conversations, like ours!
@@PunmasterSTP cool strat bro
I also took general chemistry at my Community college. Mainly because my Engineering friend, that was competitive with me in my math classes, was taking it. I quickly came to regret that decision. I had to transfer to a lower intro version of the course because I felt overwhelmed in the first lecture and I just couldn't get interested because I felt like I was just memorizing stuff instead of learning anything. I ended up getting a B on it like you because I put more time in the classes I was actually interested in. It wasn't until I took Quantum Mechanics and I knew where stuff came from, on a more fundamental level, that I got interested in Chemistry. @@JimmyGeniusEllis
Why can't teachers be like you and not overcomplicate it. Thank you sm Professor Dave Explains
I love how this video was uploaded over a year ago, but Professor Dave replies to almost all the questions. Shows great skill and dedication! 👍
you know it!
Including this
Wdym a year ago? This video was posted 6 years ago! And it's still helping many people after all these years
@@heheheheheheheheh3391 The original comment was uploaded 6 years ago, please learn to read.
@@polygongaming8859 bro shut up, don't point out like that, mind your own business goofball
Thank god u exist I have no idea what's going on in chem class this helped a lot
SAME THANK YOU HUHUHU
It's funny how some guy on youtube can explain something better than a professor getting paid $70 000 a year. And in less time too!
The only man on UA-cam who teach almost all periodic table chaper under 8 minutes.😊 In very well way .
I was studying for my first Gen Chem exam and was so confused about IE and EA but you made it so clear- thank you!
I told a joke to the noble gases but they didn't react :(
gunjan sharma I get it lol
its react...
Bahut faltu joke tha 😛
😑😑😑
Lolll
The world is so much different now that I'm less confused
Amen
absolutely!
It's always been the same..people used to try to manipulate nature, and they still do- just in different methods now.
No world is so much different in 2020!
😂
thank you for making education and knowledge accessible for students all around the world! you have helped over a million students feel more confident in chem tests, and you are excellent at explaining complicated textbook terms!!
Professor Dave you're going to get me through finals this week, love your videos!
Professor Dave for president 2020
well, i actually will be president 2033-2041. you clearly haven't seen my clip, "a president for the future - professor dave!" you can view this by searching the title or finding the "just for fun" playlist on my homepage.
Skelly Bro I'll vote!
Wait, is it gonna happen? I'm still down
The opponent will be a flat-earther.
If I was American, I would vote for him tbh
May you be merciful upon my midterm tommorow Jesus

@@SuperAsim99 i am aware how you as an athrist would consider this a "woosh" situation. I have my proof and you are to come and learn :)
Ak Mikki I haven’t heard of an “athrist” but what’s your proof?
@@luisishere987 wow .. so petty
You break things down simply, schools need to model classes this way. Excellent presentation sir.
Professir Dave. You have helped me soooo much. Ive seen sooo many of your videos. Ive been studying for the MCAT for 2 months. Ive seen your videos on physics and chem and you have saved my life. Thank you.
Prof Dave is an OG. I've failed chemistry 3 times, but it is required for my major, even though I will never really use the material for my major... Dumb I know. I just haven't really cared in the past but now I'm near graduation and HAVE to pass. His videos help explain things more thoroughly as lecture hall material can move very rapidly. And most lecture hall profs could care less about the kids anyways... too many of em lol
you can do it!
did you pass?
u pass?
Did not failing more than once affect your score? I failed two subjects (in my foundation year nonetheless) and it wrecked my GPA
when jesus teaches you chemistry ftw
yo dawg omg, i thought the same 😱
no coisidence
right lmao
HAAHAHAHAH
😂😂😂
i've been studying for my Licensure Examination for Teachers and your lectures are a big help to me! THANK YOU!
One of the best youtube vids on this topic! You summarized pretty much everything there is to know in less than 8 mins
I just wanted to let you know, you just saved me from failing my chemistry test tomorrow. Thank you for this amazing video!

How did the test go?
@@PunmasterSTP lmao bro ur 4 years late
@@DC-np5kf I actually enjoy replying to old messages where someone says they are about to take a test or needed something for a class. It's led to a few cool conversations, and I think it also boosts engagement which can help out the video and the channel. Either way, how have you been doing as well?
so did you pass the test...
Very good Professor Dave. The short animated images on the video really helps to make those harsh chemistry concepts easier to be figured out. Congratulations!
A correction at 5:55...Chlorine has a highest electron affinity, there are several exceptions to the Electron Affinity Trend on the periodic table. This is due to the size and charge of the nucleus in relation to the distance of the valence electrons, space in the valence orbital, and the variation of "shielding" or electrostatic force that is imposed on the gained valence electron by inner-shell electrons.
I like the fact that this video was uploaded 4 years ago and he still replies to all the questions, great determination. Keep it up.
8 years now
I’m taking chem honors this year as a sophomore and I have no idea what’s happening. Thank you so much
How did chem go?
yeah how did it go? hope u passed!
Bro same. I'm taking AP chem this year as a sophomore and I've never taken a chem class.
@@kiyaodekirk8744 Let us know how it goes. Btw I tutor chem and if you ever have a question, hit me up via a comment…

I wish I found you sooner! I'm not as stressed to take my exams anymore because I actually know what I'm doing now! It's weird how I learn more from these videos than I have in a whole month of lectures, and I have to pay thousands for those!
Watched this for my Chem class a year ago, and rewatching it now to study for my TEAS/HESI nursing exams. Hands down my favorite chem teacher is Professor Dave
This boosted my understanding of chemistry so much, honestly a better review for the test that i took than what my teacher made. Great video!
Ok woah this was awesome. Taking my final in two hours and your videos have taught me more than my professor has the entire semester.
I was having trouble understanding ionization energy, and after this video I understood it completely. Thank you and keep making more amazing content!
Shouldn't it be Cl< Kr< Si< Ca< K? Silicon has a higher atomic radius than Krypton
There are alot of great chemistry videos on youtube, but I think these are definetly the best. Clearly stated with clean visualizations and a good pace. Thank you so much for helping me! Your hard work shows!
thanks for the kind words!
Professor Dave Explains you are damn awesome
This helped me so much for tomorrow's quiz! Thank you so much!!
After not understanding this topic for months and months while the rest of my peers had already moved on, this video really helped me. I was like ohhhhhhhhh my gosh I finally understand. Thanks!!
your explanation is easy and smooth, thanks a lot! So I recommended these videos to my students in chemistry.
I love your videos making my understanding of chemistry so simple now
My 11 year old daughter thinks Your Dave Grohl of chemistry . You have help her no end with her studies she absolutely loves your channel
Thank you 💖
thanks a lot....a 50 mins lecture explained in 9 mins....this really helped me a lot.Keep it up sir and good luck.
I'm writing my chemistry exam in 5 days time and I'm already seeing myself through. Thank you Mr professor, your explaining this better.God bless🙌
Thank you so much! 1 hour lecture in just 7 minutes
SO HELPFUL THANK U SO MUCH, MY TEACHER CANT TEACH BUT U CAN
T_T That's a bit harsh don't you think?
StreamVid7 no, its true
Sir Richter good Explain
I was confused with ionization energy’s relation to the size of the atomic radius but they way you explained it helped a ton!
Have been following u for a yr now and am really impressed with all ur videos professor Dave 👍👍👍
This is so helpful! I'll most likely pass my Chem test tomorrow! Thank you!
Thank you so much Professor! Now I know! This is great to perfect my quiz about it! 😊😊
NekoRinNya seems like you also really needed help
Kevin Aluka yeah I did really need help. :)
Love his teaching, it goes better the way he explains. BRAVO MONSIEUR DAVID
I love you man. Straight to the point and easy to understand!
this was explained so well. best for one quick last minute revision before exams

I had an online assessment but I hadn't prepared. Honestly, this saved my life. Thank you!
Dave u have helped me so much for my chem test tomorrow. I wish I found u earlier when I was taking bio
POV: sitting here at 2:30am completely clueless for test tomorrow
this is really helpful. Helped me clear all my doubts. thank you
I want appreciate you that you have explained every single thing better than my chemistry teacher and after seeing your videos, reading the text book again makes sense😭😭
You explained really well, and that helped me a lot!
This is actually my very first Professor Dave video ever, and I have no idea how I went such a ridiculously long time before stumbling upon this man’s true genius.
you are really a blessing from heaven Professor thankyou for your hardwork , tutoring many students and making their dream possible.. Thankyou from the core of ma heart..
Well im kinda a few years late in watching this but its teachers day today and ur videos are helping me feel less anxious about my chemistry mid term exams so thank u so much for making these. Happy teachers day!
Great video, packed with information.
Having a unit test tomorrow and this will make me get a high score! Thank you so much!
Raddy Vogue you're Asian. You'll get a high score either way.

Here because ive zoned out the last month of periodic trends and exams are in 2 weeks this was very helpful
In school in nigeria mendeleev discovered the periodic table in 1869 to 1871.thanks for the great teaching ❤
Gold content at the last minute.
Will watch more earlier in future than having stress like rn 🗿
Thank you so much! you tauht me more in 7 minutes than my chem teacher did in two weeks 👍
Great....love the magnet pulling off the electron....great illustration!
This was beyond helpful and right on time omggggg. Thanks Professor Dave !!!🥺💕💕🥼🧫🧬🧪
thanks al lot professor..that was a wonderful presentation..
Absolutely amazing
Clear cut walkthrough of trends in 8 minutes is mind blowing! I was searching for something like this
I am studying in class 7
Our school is just giving so much pressure to learn all these topics and Even the teachers do not explain well. And I am a new student also so I have missed out a lot of physics, chemistry,etc and all that. So thank you so much professor Dave for teaching with so much affection and concentration. Thank you so much
I am having my exam on these
topics tommorow and I am really worried and scared. Hope this will help me a lot.
Thank you 🥰
Thank you, professor dave, i found your video interesting. I never be good at chemistry in high school, but i have had the curiosity to learn chemistry indeep. Here, i am, at the age of 37 starting to learn chemistry from the beginning.
Professor Dave, you are awesome. Even in these old videos you are explaining like a god in the education field. Imma give a class about this, and this explanation works so well for me. You are a big inspiration for me. Thank you so much!
Chemistry is no more a chem'MYSTERY' to me!thank you professor dave
you are really good at giving "chetech" students an overview of every topic.
Oh my god you’re the first person who explained chem so that I could actually understand it so thank you so much!!!
great explanation dude..thank you soooo much!
I love you, you make learning easier and fun!
I had no idea what the teacher was talking about in my class. But now I understand much more better.❤️
Thank you so much! This video explains everything so concisely.
