11th grade Egyptian student here! Honestly just thank you, my exams are in 2 weeks (even tho we're in the middle of a pandemic!) And since the beginning of the year I've been watching and recommending ur videos to help us with chemistry. Thank you!
@titaniumtries4893 Didn't get into my dream college, so I can't be a med student But I'm almost done with a bachelor's in microbiology Watched his videos through all my chem courses tho, ever the lifesaver!
Thanks professor dave! I am beyond blessed to live in an age where I can search the internet for better explanations than my weird and confusing textbook.
Professor, I really admire you. I want to be like you someday. Great teacher! I didn't understand my chemistry during my high school and college days yet, I am Science teacher. I have a lot of questions to ask. I salute you. kudos!
Our Chemistry and Physics teachers always links us to your videos. I'm so lucky to have discovered your channel. And hey, there was a time I was trying to learn Italian, I was shocked that you appeared on the search results! Truly Amazing.. 💙💙
Hey Dave, really appreciate your videos. You have been a huge help not just for quick reviews but also for understanding difficult concepts in short and concise ways that have helped me in my first year of Uni. Can you make a video about molecules that defy the octet rule, please? Their dot structures and maybe the reasons. In general, it seems that my professors love to throw the difficult "disobedient" circumstances at us when it comes to exam time.
i fell asleep during science class and woke up just as this video was playing, and my glasses-less, newly-awoken mind yelled out, "IS DAVE GROHL TEACHING ME CHEMISTRY RIGHT NOW"
Oh!! I'm here watching this after 8yrs and I'm sure that even my childrens are going to watch this master piece... thank you sir this explaining, it was really a life saviour for me..Love from India✨
I was looking for the topic * Electronegativity" and came across to your video "The Periodic Table: Atomic Radius, Ionization Energy, and Electronegativity* found it helpful because it covers all the topic that i needed to prepare for my test. once again i click on the link to learn about Lewis dot structures, but again this video covers all the topic that i need to know for the next test! thanks!!!
+Professor Dave Explains I did even better! I actually told my Chem. professor how helpful your videos were. She thinks your videos are great, and she plans to use some during her lectures in the future. She says they are really consistent in the quality of material, and she loves them. So, now my whole class knows and her other students will too :) Thank you again.
Chemistry Professor Jesus saved the day because I am doing my online homework last-minute and I had no idea how to do it. This Man has saved me from failing. Thank you.
You are so incredibly helpful, I cannot begin to thank you enough. I have had a hard time figuring this out when all my classmates seem to get it. I wish my teacher would play your videos in class.
THIS JUST SAVED MY LIFE!!!! my teacher was getying frustrated cuz i didn't understand, i wasn't there to learn about, so thank you very much for this video
I've loved learning with your videos and I'd want to say that it's been incredible honore to have a teacher like. Hope I'll be thrilled to learn more stuffs like this one in an effective and manifesting way.
Cash group numbers. Spend single bonds. Electronegative ends. Eight electrons each. Extras inside. (Group - Bonds & Dots). Minimise (turn lone pairs to bonds). An easy way to remember.
Thank you so much!!! I was like what the hell is my chemistry teacher talking about??? I'm a 6th Grader and I didn't even understand a single word. But I searched up on youtube this is just perfect. Thanks a lot.
Your videos are a big help! I hope my teacher shows videos like this to the class instead of just showing powerpoints. Because its not just me in the class who dont get her lesson lmao. Thank you big time!🙏😊
so boron does not follow the octet rule, it only has three valence electrons it will typically only accommodate three bonds. if it has four bonds, like in borohydride, it will have a formal negative charge.
that's right! the octet rule doesn't apply to boron. really, it doesn't apply to very many elements at all. carbon, oxygen, nitrogen, fluorine, argon, that's about it.
Professor Dave Explains also saw another version of SO2, one of the O atoms has a single bond leaving 6 lone electrons. Hence, the sulphur atom has 8 valence electrons.
Hey Dave, I had trouble with the comprehension question for SO_2. I found another guy's video specifically about that (xDG8EQ2Fq8w) and he said it doesn't have double bonds but rather "hybrid resonance bonds" - whatever that means. Is that correct or is it nonsense? Does that mean the answer you gave is an oversimplification? Speaking of simplifications, you mentioned that phosphorus and sulphur can both form five bonds. That didn't make sense to me, so I started researching it online and it seems to be a complex topic but possibly related to orbital hybridization - is that right? Personally, I am not sure if you should include such factoids without at least a passing explanation, to avoid just this sort of confusion I experienced. But maybe there is a good reason, and this is just something which I should be expected to know and/or accept without understanding. If so, at least a disclaimer about that could have saved me some trouble. Anyway, I really appreciate your videos in general. They are immensely helpful to me. Thank you.
Elements in n=3 and above have access to d orbitals and can expand their octets. In truth, very few elements obey the octet rule, and even those don't always obey it. It's best to disregard the rule.
Me who goes to a private school that has good info for all subjects: *Dies of tiredness and confusion* This dude who explained it all easily in 4 mins: *Revives my soul* Also me just speechless: *_"Amen to that-"_*
This is what our teacher taught us in 10th standard now i'm in 12th grade and forgot what it was like ...i think after his explanation i vl never forget this ...thnx master !!🫡
I’m watching this video for help with my college chemistry exam. You said you can tell the amount of valence electrons by counting from the left and I audibly went “what?? DUDE!! I didn’t know that!!”
Just subscribed. You're so underrated. Please do what you're doing as you're fantastic. Why are we making stupid people famous? And why do you have so little views .....
i couldn't agree more with all of the above points! please tell your friends to watch my channel instead of today's celebrity of the month! my hair is just as good as theirs :P
this is a very good video - definitely giving it a thumbs up, but its just a liiiiiiiitle too advanced for where I'm at in my intro to chemistry class. just slightly above where I'm at. Still good info though!
Chemistry Jesus 😂😂😂 man thank you so much for this video I've learnt more in 1hr of watching your videos than a whole semester in school 💯🔥🐐 thanks so much
Thank you chemistry jesus
+Moshingrobot you are welcome, my son.
The true savior.
Professor Dave Explains Can you tell me the # of domains & bonded atoms in SO2?
So true, he explains something in four minutes and my own chemistry teacher takes an hour and a half to explain
God exists. This is proof.
So I forgot this channel's name so I searched "Chemistry Jesus" on TH-cam and here I am, I found what I'm looking for.

i watched this video for help and genuinely cried at the beginning intro for how majestic it was. I literally had tears.
I have my exam tomorrow, this has helped me so much!! Thanks Professor Dave:)

This helps a lot, my teacher didn't teach this in class and the year got cut. Thank you.
Sigma bond 🗿
When my teacher explained this to the class it was a shipwreck but when I watched your video it became a piece of cake. You're Incredible!

Thank you Professor Dave for making concepts easier..
Kindly try explaining the answers of the comprehension...
dang you really are the chemistry Jesus
finally found my very first favorite youtube channel
When you're a scientist but also religous:
Professor Dave's channel is underrated -- he's really outstanding. I'm happy being his fan before reaching 1.3 M subscribers
Your videos are a big help! I hope my teacher shows videos like this to the class instead of just showing powerpoints. Because its not just me in the class who dont get her lesson lmao. Thank you big time!🙏😊
Thank you so much for saving my life. My chemistry textbook is literally shit, but this makes so much sense.
actually its boron one at some 4:05
so boron does not follow the octet rule, it only has three valence electrons it will typically only accommodate three bonds. if it has four bonds, like in borohydride, it will have a formal negative charge.
I like how there people who make informational videos that are still helping people after years later along the line.
I’m going to give you a high rating on rate my professor, thanks Professor Dave
Where did u get ur shirt
in BF3 boron didnt satisfied octet rule (only shared 6 electrons instead 8) why?
that's right! the octet rule doesn't apply to boron. really, it doesn't apply to very many elements at all. carbon, oxygen, nitrogen, fluorine, argon, that's about it.
In battlefield 3? lol
LLOLLLL
Professor Dave Explains is sulphur in the exception list too? I see 10 valence electrons for it in SO2.
Professor Dave Explains also saw another version of SO2, one of the O atoms has a single bond leaving 6 lone electrons. Hence, the sulphur atom has 8 valence electrons.
this cleared up about 2 weeks of lectures. thanks
bless your soul
wow consise and crisp along covering all the points thank you so much!

For SO2, if we use both side double bond, shouldn't we delete the 2 dot upper S?
No it has six valence electrons
