- Did you know that geometry was invented by molecules? It's true! Until the first stars went supernova and littered all the elements across the cosmos, everything was simply spheres, from protons to stars. But then, under cooler planetary conditions, atoms came together to form molecules, and in doing so, they created the first shapes the universe had ever seen. Learn about the different shapes that molecules can make!

Your 6 minute video taught me more than 6 hours of lecture.
Same here. Amazing video !!
the same here also
Same here also...
maybe because you are not paying attention
Pay attention in class
Anyone watching it on 2024
I got a test tomorrow
Yessir
Yeah for class lmao
Hall yeah
Yep got the test in 20 minutes
I personally think Professor Dave videos are better than Crash Course.
Crash Course is distracting and fast, while Professor Dave explains and reviews.
Thanks Dave!
in my opion they are both good and different Dave is better at giving details while crash course is better at giving summerys.
@@erikburzinski8248 i agree
I think crash course is good if you have time to waste. Or if your way of learning is by story
I would say crash course is more for entertainment, not for revision.
its called crash course for a reason you know, most people use it for review or to get an idea of what they'll be doing.
Professor Dave should have my professor's salary. My prof would not teach this to us and would say we should have known this already because it was taught in high school even though it was not.
Miss Milka I’m pretty sure Professor Dave makes more. If he doesn’t, I declare bullshit on every college.
the education system in the uk is much different we learn this in high school
@@abdirizaqmohamed344 They probably learn things that you don't learn in highschool tho. I am learning this in highschool as well but there's really no point in bringing that up.
@@kaos7012 True...
out of topic, but is that lia
it’s time for finals again so you know what that means! binge watching professor dave’s videos!
OMFG I GET THIS THE NIGHT BEFORE FINALS!! THANK YOU!!!!!!
1 year later here I am doing the same lol
same lol
Same lmao
Same haha
sane bhuga
I'm finding this video suuuuper helpful for my chem midterm tomorrow. It's also posted on my birthday four years ago heheheheh :D That must mean good luck. Thx Professor Dave!!!
I might pass my chemistry final tomorrow thanks to u Dave. Thanks u!!!!
Definitely not passing English though.
@@BB-gr7ug oh my god im rolling☠😭
I know this four years ago but did you pass
@@rudbergalitzine lol yes i did !
@@kristynpaige4151 lets geddit congrats!
I never understood this topic in the class but now my concepts are getting crystal clear.
Thank you very much Professor Dave.
i have scoured my lecture notes, textbook, ACS guide, and watched probably 30 videos on molecular/electronic geometry. all were missing something important and this video ties it all together. particularly the electron density explaining the spd hybridization. PROFESSOR DAVE YOU ROCK!!!
Sorry to break it you but nah then u r just dumb
You are honestly one of the best teachers for chemistry I have ever come across. Thanks so much!
Professor Dave you are literally the best chemistry teacher! I had this topic in many hours either in school or now in university and i watch this and it makes just sense! UNBELIVABLE!
your videos are literally the best source of information, and best explanation of chem concepts that I have found. They are detailed, yet not overwhelming, and the comprehension checks at the end are Au!
Oh my goodness, this lesson helped me so much! I was really struggling with this topic in my chem class, but now it makes a whole lot more sense! Thanks Professor Dave!
ahh this video just made everything so much simpler. your explanation and visualization really helped me a lot. i have spent quite some time after these topics but now it's all a lot clearer in my head. im so glad i found this channel, thank you so much for your efforts :))
This is amazing! I understood the lesson better by watching Professor Dave's videos rather than reading our learning module. Thanks, Professor!
I've always learned and have been taught the the lone pair repel more than shared pairs which accounts for the difference in the molecular geometry from the electron geometry. Not because the lone pairs take up less space.
But a good job explaining electron geometry.
My book of university chemistry says lone pair takes most of the space of central atom thus repulsion between lone pair is more
Just when i thought all hope was lost, in an attempt at a last minute cram session at 3:56 in the morning before finals chem jesus blessed my mind with weeks of knowledge in a 6 minute video. Praise be!!!
chem jesus lmao
HAHAHAHAHHAHAHAHAHAHA
@@peterroberts7832 The only god I praise😉.
Was looking through videos to learn this and I definitely clicked the right one. Thank god. Thank you for all the time you put into this short video.
All you're videos are very good, but imo opinion this one is incredible. It seems to pack in a ton of information and the learning tools illustrate the material so well.
I'm constantly sharing your channel with everyone. Thank you so so so much!!
Hi Prof. Dave! Your explanations are lucid, thorough, and your voice is gentle yet confident- making the whole combo extremely useful and pleasant. I can go watching/learning from your videos for hours.
I am going to support you on Patreon.
Also, would you please make some videos on music theory? I am sure like me many, many people would love to watch and learn music from you.
Thanks in advance for the support! Yes absolutely, music theory is on the list!
Chemistry jesus.
That electron domain trick really simplified molecular geometry for me! Thank you so much!!
thank you professor Dave, this was really helpful for a student trying to get in a medical school via NEET (med entrance exam in india)
heyy are his videos helpful and enough for neet chemistry?
@@zake9793no
I've been in hours of lectures and been studying this all day today, and this is the only video that made me finally understand it.
aaaa tysm professor david ! I didnt knew the "count the number of domain electrons" trick for hybridization and it helped sooo much !! Thank youu! Stay healthy n safe!
I am a long term sub that got handed a chemistry class, you are totally teaching me so I can teach them. I love you videos!
Thank you for this video. I have been spending hours reading my textbook and looking at other videos and this one finally helped me get this.
Where were you when I needed you last year?????? This helped me so much!!!!
Always good to know you're there, Dave 🎉
I swear this hybridisation topic has been going on in my class since 2-3 weeks, I learnt everything in this 6 minutes video that they were teaching since weeks.
My teacher doesnt even teach us, makes us teach ourselves it out of an outdated text book. You taught me more than he has in a whole unit. THANKS!!!
Bless you for these videos this makes it so much easier!
And here comes the next wave of Chemistry students before finals! Thank you so much!
omg, i finally got it! when my teacher was going through this, i was so confused about what’s going on, thank you for this video!
Well thank you yet again, Professor Dave. I am taking biochem and needed a review.
I'm teaching this to my high school honors chem class right now, and I was looking for the best video that would illustrate this concept in a really concise manner (since we've gone over orbitals and electron configs already). I think this video will be helpful!
This literally just saved me, my chem final is tomorrow and I finally understand this instead of just guessing and getting it wrong, THANK YOU SO MUCH
Thank You so much professor dave.... Im a nursing student and about to take biochemistry and i binge watch the general chem and organic chem playlist and it helped me a lot!!!
We need a teacher like you!
sir u have explained the big concept that too in a very short period of time. It is really amazing.
amazing explanation professor 🌷
Thank you so much professor! that helps a lot !
I sincerely wish I would've found you earlier this year....
thank you so much Dave..... for making things so easy...
Thank you for all your videos, you are making me more knowledgeable and helping me skip 80% of trial and error, as I am learning about chemistry and physics on my own. Keep posting, and I’ll keep learning. Thank you!
This actually makes sense, thank you!!
Thank you!! I finally understand this.
Thanks! I've been searching for this information!
sir ur the best professor.......the way of ur explanations is amazing
Thanks so much, what I should have learned over the course of 2 days I learned in 6 minutes.
great explanation Dave
Ok not even lying, i saw a meme about him being a chemistry Jesus and I came here because I got a chem 30 test tomorrow thinking what do I have to lose. Little did I know that he has FIVE VIDEOS OF WHAT WE ARE LEARNING THANK YOU CHEMISTRY JESUS
Now I know I am going to ace my grade 12 chem exam tomorrow!
Omg! THANK YOU THANK YOU THANK YOU. You explained it so much more easier. I am now subscribed 👍🏾
another nice video of yours. enjoyed it very much
Uploaded 6 years ago but it's still so helpful😭♥️. Prof Dave u the best
4:58 THANK YOU FOR THIS AMAZING TABLE OMG
Nice chem video once again. My friends are watching your chem vids!
i simply don't get why many teachers make learning things complicated.it takes them many classes to explain this.am happy to know that iv found a way out of reading huge books............thanks dave.#just found this before exam
Thank you very much.
Been struggling to get the concept
Now it's crystal clear
Thank you so much for these videos. Honestly you've saved countless grades, and not just for me!
Your videos teach me more than I learn in college. Thanks so much.
An amazing taught,I really appreciate,thanks in advance,you have opened my mind
YOUR LECTURES ARE EASY TO UNDERSTAND. THANKS SIR.
one minute in I'm just like so grateful this is great, do you have an orbital video?
I found it thanks!
Whoa! TYSM! LOVE it! With your 6:30 mins explanations, I finally understand the 3 one hour of miserable chem lectures! :) I don't know chem without you, Prof. Dave! ^_^
I really don't know what I would do without you
I wish that I found ur videos before tomorrow is my exam but I still appreciated cause i found them 😍😍😍😍😍❤️
Dave you really helped. Thanks man!
time to leave school and join professor dave membership
more power to you..this is essential to my classes
Thank you so much!! This video really really helped me! ❤
Thank you Professor. This video is really help me a lot
Putting shapes in the right holes finally paid off
Lmao your general chem playlist teaches me more in 30 mins than 3 weeks of class, you are the sole reason I’m passing chem
Thank you. Your explanations click in my head and I get it!
very nice explanation
finals are next week and I just now understand this thanks to you
12:23 AM I just finished watching this video and it has helped me tremendously, THANK YOU SO MUCH!
Checking Comprehension at the end is very helpful
sp Hybridized = linear| no of electron domains-2
sp2 Hybridized = trigonal planar(120)|no of electron domains-3
sp3 Hybridized = tetrahedral(109.5)|no of electron domains-4
sp3d Hybridized = trigonal bipyramidal(90 and 120)|no of electron domains-5
sp3d2 Hybridized = octahedral(90)|no of electron domains-6
thank you so much. i always look forward to the theme song.
Your videos make me understand things I lost hope to understand..Thank you very much
well done
Excellent method of teaching
Thank you Professor Dave, very cool
I think that you just summarized a month worth of classes in just six minutes. Thanks so much!
the first 10 seconds of your video taught me more than all of university combined
Thank you. Very helpful.
I love you man xD , Its badly explained/organized in the book, and I used to sleep in all the lectures, now I finally understand it.
THANK YOUUUUU! I wish you were my Chem teacher!
This video is amazing!
Amazing sir I love your teaching style in this lockdown period I am totally depends on you
Thanku thanks so much sir
I subbed for that intro alone. Classic!
Thanks Sir.I understood what's the difference b/w electron geometry,molecular geometry and shape.
Professor Dave helped me with Italian, and now he’s saving me in Chem much respect
Great video!
Your way of explaining is great
Dude you're the best, keep up the good work. God bless you, really.
