That electron cloud illustration with the camera was too good 🙇🙇🙇
Agreed. Cemented my understanding quite well. Wish my college quantum electronics lecturer understood this
Soon I will teach this to my little brother. Thanks a lot
@Dr Deuteron Actually, I think I will add concrete
@Dr Deuteron Noted Sir
@Dr Deuteron İ perfectly understand your position. However you should note that most commenters here are not professional chemists or physicists but people who interacted with this material in high school or college. TBH my lecturers/teachers never presented the material in a way that would stimulate interest or understanding. I always wondered whether she understood the topic. The video has sought to simplify (maybe oversimplified) the material using analogies anyone would understand. That's why it has gotten such positive reviews from most commenters here. While I think that your efforts at providing detail are laudable, I believe that these efforts would be more useful if directed at encouraging teachers/lecturers in schools and colleges to better teach the subject matter. If they did, we probably wouldn't be having this discussion.
I wish this had been taught to me so clearly when I was in high school and college.
When I went to high school, the concept and understanding was different. We actually learned orbits, not orbitals, and electron position and notation wasn't as it is now.
Hmmmm, what if the reason we can’t pin down the location of the electron is because it passes through 5 dimensional space. What we observe is the state of the electron at each snapshot in time.
In the double slit experiment the electron takes all possible paths through to the target. We only know which path it takes if we observe it.
What if that is why we can’t also pin down the electron orbital properly
Our 4 dimensional world is a shadow of the 5 D world outside of ours. Just as the 2D world is a shadow of the 3D world.
Our 4 th dimension, time, may be a shadow of the fifth dimension.
Time itself seems one dimensional. It only goes one way, from our perspective. Top theoretical physicists say that there is no real reason why time could not flow backward.
Maybe it does, we just can’t see, or observe it because we are one dimensional, we only observe the world in the forward arrow of time.
An electron seems to transcend the physical,world taking al, possible paths through the two slits if not observed.
Maybe the electron cloud,if observed properly, can give us a hint of what the fifth dimension may look like. Kind of like trying to observe a three dimensional world from the surface of a two dimensional shape.
Just some thoughts.
@@openwaters2988 Do a search for the "One electron universe", where theory suggests that every single electron is the same electron, that travels through space and time, to be in all places at once.
It might go a little way to define further what you're saying.
Utetopia yes, I’ve heard of that, couldn’t find the name of the theory though, thank you. That’s sort of what I am referring to. I will check it out.
My school was for marks only.now I get the worst marks.
I recall how I felt betrayed when after studying Thomson's plum pudding model, Rutherford's nuclear model and Bohr's orbital model in freshman high school and understanding that the electron is a particle of charge. Okay. Then we get to the senior year and we're told forget all of that an electron isn't a particle orbiting a nucleus but it is a cloud of charge surrounding the nucleus. Okay. Then I get to college and was told well its not a diffused cloud of charge but a probability of where the electron really is. 🤦♂️
the hilarious bit is, all these ppl telling you "this is how it is", and absolutely all of it is conjecture that has little evidence, none of it observational evidence, and only a single maths proof to support it.
U just summarised the whole thing!
And then schrödinger becomes to say “yea!!! may be is there or may be is not, to be sure don’t look at it”.
Okay this is all I want to know
If all the previous things were wrong why did we learn them.
@@nihaal7750 Wrong is not really 100% correct either. It's just different shades of detail, some concepts are easier to understand if you use the simpler concepts of the atom. So that's why, the more you move into other subjects you will need more detailed (and more accurate) definitions of the atom for the other theory to make sense.
Where were you!? I was looking for you all these years.
Hahahahahaha!
me too
physicist: where are you?
electron: im at the s orbital at once, until you measured me
einstein: you are mocking me.
bohr: you are both alive and dead at the same time
einstein: does the moon not exist when your not looking at it?
physicist: ok, let's adjourn..
I think I teared up watching this. A) Because it was so complicated yet so simple and honestly so beautiful and mindblowing. We discovered this stuff! This is the universe! I'm surrounded bt this! And B) My teacher's've been constantly and REPEATEDLY trying to explain this to me - you know all the XYZ axes & stuff but there has NEVER been a proper visual for years & I never really grasped this concept. I didn't even know electrons moved randomly.
I can't tell you just how thankful I am. Thank you!
There were "proper visuals" years ago. I have a physics degree from 40 years ago and the non-existent visuals you refer are there in plain sight. The problem is that you didn't bother looking for them.
@@johnpearson3761 ouch
@@johnpearson3761 what you say is true, but still some responsibility goes yo the teacher as well.
Instead of drawing at a board they can use a projector or smart board for animations.
Or even print outs in class.
That is exactly the way to describe science... Simple and complicated. We might decide to settle for the simple or we strive on to simplify the complexiities
Neither my high school nor college education on this gave me the intuition of orbitals and hybridization, but this managed to do it in 5 min. The visual alone pretty much made this so clear (camera snapshot example and combining the orbitals)
classic "i never payed attention and now complain"
@@bobfake3831 No. I slaved over lectures and office hours to try to understand hybridization. This video was the first time it simply clicked. I wouldn't blame my professors or TAs as everyone learns differently.
This channel should have views in millions........thanks to them for creating such an understandable visualisation of concepts
unbelievable lecture. waited 50 years since my college chemistry to learn all of this. Wish we had these lecturers in my time!
Nobody is too old to learn... trust me you will learn a lot more if you live hundred years later from now
THANK YOUUU !! THANK YOU SO MUCH. MY TEACHERS AT SCHOOL TAUGHT US HOW TO WRITE THE ELECTRONIC CONFIGURATIONS FOR ANY ELEMENT WITHOUT EVEN TELLING US WHAT ARE THE BASIC "MOST IMPORTANT FACTS" BEHIND IT. WHEN I WENT THROUGH THE TOPIC IN BOOKS AND ARTICLES I TRIED TO VISUALISE IT AND YOUR VIDEO JUST MADE MY DAY !!
THANK YOU AGAIN !
KEEP UP THE GOOD JOB 👍
this video has to be played in every chemistry class
Please upload video on Schrödinger wave equation and wave mechanics model of an atom ..
got a randomly recommended... but so glad to find a channel like this... thank you for your efforts
Honestly one of the best videos to visualize this chapter thank you so much!
as JEE aspirent i literally needed this thankyou for "visulization"
thank god suggesting this even after 6 years of uploading
YOU'VE SPENT 2.5MINUTES TO SOLVE ALL MY QUESTIONS ON ELECTRON SHELL,ORBITS AND SUBSHELLS.I HAVE SPENT ALMOST 4HOURS ON THIS UNTIL I'VE FOUND THIS VIDEO THANKYOU SO MUCH.This is my first time to leave a comment on TH-cam thankyou so much the animation is so good
Absolutely superb explanation, and I'm a physics major. This was so well explained. I wish, I had this explained to me when I took chemistry and quantum mechanics. Students today have no excuse for not doing well in school... None.
The teacher will have to explain how the orbital shapes are determined though. That requires quantum mechanics, but students don't have to understand it...they just need to know that is how the shapes are determined.
This is one of the best visual representation of chemistry, Thank you.
Seeing the electron zig-zagging around the hydrogen nucleus, and the overlapping "clouds," helped me SO much. Thank you.
This video has enlightened me about: atom, electrons, orbital . Thanks a lot.
Thank You! it took me quite a while to search for how an atom would look like with al its orbitals...after being repeatedly told that atoms couldnt be visualised,has no viewable image ,needed more imagination etc and finding this video with such on point illustrations and clear explanation was really helpful.Kudos to the team 👍
This helped me a lot. Ended my 5 year long confusion. Thanks to the creator of this video and the channel
Thank you. This video makes the visualization of orbitals and electrons attainable for students.
This video is damn important for chemistry no matter how good your teacher is but the animated video help us visualise and understand this clearly......
Thanks a lot...I was looking for explanation & video like this for years...really thanks a lot...finally understood the orbitals...
I. LOVE. YOU. the hard work put in this video will have eternal fruit, iloveyouiloveyouiloveyou
I love you too (to the creator)

Ok...
what a video !!!!!!!!!! can not express my gratitude in words
Thank u so much.. I had been struggling with this orbital concept for 2 months but couldn't understand the position of orbitals and sub-shells in an atom.. But your video made the concept really clear to me.. thanks once again..
I like your profile picture 👌😍😊🕊️
After finding thousands of video this the only video which made me understand this ! ✨
Small correction there, Aufbau is not a verb, but a noun. It can mean setup, buildup, installation, but also composition.
The verb is "aufbauen" - "to build up"
These videos are awesome and stupendous. Thanks for these vivid illustrations. I wonder if you could provide similar videos on why these orbitals s p d f have such peculiar shapes in 3D space. To the extent I know, these shapes are the results of three-dimensional extensions of the different modes of vibrations seen for a particle stuck in between a one-dimensional potential barrier using the time-independent schrodinger equation. But to view the creation of these 3D shapes in process from the one-dimensional and two-dimensional modes of descriptions would not be less than an amazement. I hope your efficient team would be interested in such illustrations. More or less, I find my point on the same lines of the above comment.
Thank you for your feedback! And We will look into that topic for a future video.+Rahul Gupta
very good... nice.. zabrdast
Wow... What a video !! Amazing explanation... All you need to know about Atom in under 15 mins. Thank you Sir !!!👌
After all these years, I have a very clear understanding of this confusing topic.
Very detailed video.
Thanks. 😀
This explanation was so clear and easy to understand. I was searching lot of videos to understand this topic but atlast I found. Thanks for ur beautiful explanation. upload more videos regarding chemistry
best explanation I found so far, 3d helps so much
Hats off to this video which explained such difficult concepts in such an easy way.
Truly amazing explanation sir.
The best video I've seen on this topic, thank you so much
The explanation has been simple and clear, thank you so
The explanation and graphics are immaculate 👏
Until I saw this CGI of Orbitals I was still a bit lost. The integration of CGI with an explanation really worked for me. Great learning tool!
Clear Lucid explanation.Thank You !
under rated video. same words as below expresses my feeling towards this video.
Simple and clear. I liked the Graphics of the orbitals being added together, but think it would be even better without the contast robbing background. Still very good though.
best explanation of atomic structure and electron configuration
Many many many many thanks , it is really good , it is the best video to understanding the position of orbitals
very very beautiful and good explanation. thank you so much ....
please more video.....
mere doubts clear ho gaye sir. Kisi teacher ne aise nahi bataya. THANK YOU SIR
This video was literally very helpful👍. Loved watching it.
Very very big thanks to u. This video is really really best to clear the concepts.
An excellent description of the making of electron cloud👍👌 Really loved it sooo much. my 4 months' doubt cleared in 5 mins! Thank you.
THANK YOU SO MUCH!!!... this explains it SOOOO clearly ....
This is the best explanation I've found on quantum orbitals.
I used to hate chemistry because I was unable to visualise it but this video just made me chemistry lover ❤️❤️
Thank you👍I am gonna share this with all my mates.
Thank you so much sir ..
All doubts cleared 😃😃
Excellent presentation
Oh my god...finally after so many years of studying these..I finally get a new vision to look at orbitals.
amazing.just cant imagine myself having all those misconceptions about orbitals.simply enlightening
Thank you!! So well I explained I finally understood not only electron configuration but the periodic table!
Great job with this video! Thanks so much for sharing!
Thank you so much for this video. This video has helped me finally master this section of Chemistry
Great video. If you have to remember just one thing about the subject for life it is this:
The orbital is a three dimensional region around the nucleus that indicates or encompasses the probable locations of an electron 90% of the time (in other words the orbital is a 90% or 0.9 probability pattern of an electron locations around a nucleus).
what a great effort & struggle live long SIR
Your explanation is great
I like these types of videos
Imagine how much he work hard to make this video
Thank u so much man ... very clear explanation ... back to back with the great representation 😁😁
I will go back in time 4 years ago and teach myself from this video.
Great explanation! Good job!
Great great great explaination
that intro was so epic wow i am impressed!!
i agree like this ocmment
like comment1
!!
!
real!!
a very nice lecture not only explain atomic orbitals but quantum understanding of atoms and subatomic particle
So well explained.....👍
It is the best explanation that I know, it's the best atoms video
Thank you very much for your excellent video. I will share for my students
Best video I have cleared my all doubts thank-you 😊😊
thank god i understood veryyyyyyy clearly the difference between orbit and orbital. excellent explanation
This video is awesome , nice and clean explained hard topic
Simply awesome.
Great video. This helped so much!
Very good. All that remains is to mention the Linus Pauling Diagram, which facilitates the distribution of electrons and is a direct consequence of this knowledge.
Found exactly what l wanted!!! Thank you so much sir!!
Great explanation! !😊😊😊
Awesom sir...and thank for made easy in my chemistry....... From India 🇮🇳
Can watch this video for million times 😍😍..........Such a nice way of explanation. Just really loved your video & expect more such videos.....

Super cool videos you cleared all my doubts
Great explanation
5:00🌟crystal clear...thanks a million🥺💯
Best explanation..
Thanks you Very much and lots of love for you!💙💙
I'm was searching this answer almost for 5 years.I've searched many times in youtube and asked my high school teachers but couldn’t find it.The explanation in our country's writers' book is also not clear.I've found the perfect explanation today.
And I've a request that keep uploading more and more videos like these sophisticated concept.I've already subscribed.
You deserve lots of subscriber!
Geeez. The best visual and explanation of orbitals I have ever received.
Can't thank you enough for the video 🙏🏻🌸
2:42 that's really interesting, it'd be nice to hear more in-depth specifics about the complex math to calculate those orbitals...wish you'd have went into that
Amazing detailed explanation well done!
Amazing, thank you!
thankyou very much .i was very confused in this topic all my doubts are cleared from this video. thankyou so much
You are awesome man
Continue 😍😍😍
Your video was very gread and helpful for me. You have done a gread job.👍
