Gosh, I wish you were my chem teacher. You do an excellent job explaining concepts.
YA!!
he is Incredible
I wish he was mine too, my teacher is very nice in all, but explains everything in the most complicated way

You sir, are my second science teacher.
Adamant Pancake for me too...
Shu Kurenai, your name is the exact same name as my favourite character from beyblade
I agree
who is your first teacher?
he is also a math teacher :O
Mr. Khan, You don't know it, but my 7 year old granddaughter will be watching you as her math and science Instructor! I appreciate you and your website. This is so informative, the visuals and explanations are just superb! Thank You! I am a Baby Boomer and if I had had you in High School as a Chemistry Teacher; I would not have dropped the class!!!
Thank you soooo much! I just found your channel, and I am not sleeping tonight.. This is the first video I sat through, and I feel so smart now! I have never taken so much notes.. The color-coding is sooo helpful. Thank you very much.. May god bless your soul..! :)
calm down
***** let him believe what he wants. At least he's trying to educate himself.
I am a 'her,' but still thank you so much..!
***** She also never made an actual argument about God...she was simply expressing gratitude in her own particular way. You just took an opportunity to jab at her over something she said for some reason.
Thank you. That was really kind of you. I really appreciate it.
I'm gonna start running at walls in hopes that one day I'll catch the atoms off guard and phase through
😂😂
not a lot of people can teach like you...you are truly gifted..teaching is an art..
to sum it up everything is nothing and nothing is everything
seriously !! best explanation ever better than most college professors
i love khan academy ! thank you soooo much!!! u guys literally saved my grades!!! ♡
@@kashifnadeem2137 ?
Thank you, sir! Ive decided to go back to school and after a six year absence and having never taken a chemistry class I wanted a nice little crash course and this helps tremendously. Thanks again!
Me too. Starting after years of high school ,but im inspired. Good luck to us
It's nice when you're 36 and you still find something mind blowing.
I don’t even need to go to school, your lessons are that good. Thank you so much!
Good to know people are still watching in 2023
Thanks Man I Learned this In 8 grade In Now in hs I'm learning biology in 9 grade Thanks Again god bless you
Wow! I am so glad i found Khan academy! I am considering going to med school in a couple of years and am faced with having to remember everything I learnt years ago in order to even consider stepping foot in an MCAT prep course like Kaplan. I have six weeks off coming up and will spend my time devouring all this chem, bio, physics videos before doing my Kaplan baseline assessment. After viewing this first video, i can already tell that this will all be a major, major resource. THANK YOU!
You mean God bless their atoms 👀
been 12 years did u do it
Man, you're amazing! I am taking Chemistry for Highschool right now and it doesn't really make any sense. So when ever I get stumped I know that I can ALWAYS get help from you! You have made Chemistry more interesting for me! Thank you SO much! You rock and I'd recommend you to ANYONE! :) Thanks again!
are you alive sir?
This is awesome! I have already graduated from college many years ago but I didn't ever understand chemistry the way I should have. I just memorized everything. It's so nice to come back to study this without pressure of exam and having a lot more resources now.
the amount of times you've saved my grades is astonishing
Oh my God. I'm enjoying your classes SO MUCH!
Woahhh as a member of the christian community, i suggest you do not use God's name in vein.
(this is a joke, if you couldnt tell)
Omgosh
Where are you now it’s been seven years lol
@@fatimahaltamimi6069 NO WAY LMFAOOOO
Now were getting somewhere! Awesome! Thanks!
I'm taking Inorganic Chemistry this summer... then taking Physics, Calculus, and Organic Chemistry my Sophomore year of college to get the pre-med requirements done. It's gonna rock!
Amazing and so easy to understand! Thank you so much!
Awesome, I wish my classes of chemistry on HS were like this
Wow... Kahn, it's getting to the point where I'm jus watching your video's for my own amusement. You're very easy to listen to and your so clear about everything, I enjoy your video's for so much more than just my education. Thank's a lot for bein born :)
Totally subscribed! This is important information that i regrettably didn't pay so much attention to in high school! Thank you for this.
amazing dude!! we are just learning this on my school!! only you explain it MUCH better than my teacher!! OMG thx!!
Your method of teaching is well put. I study Physics off and on, I'll check out your other videos.
"We're empty" the lyrics was the first thing that came to my mind when Sal said most things are empty space... Mind blowing
who else watching in x2 speed
Not m3
From now on I will enroll myself in Khan Academy. So great, many things I have learn from Calculus to Physics. May God bless you. Thank you!
dude awesome ending. you completely Blew reality away from me and left me on the edge of my east. It brings so much joy to me understanding bits of what you showed.
Grrreat lecture. I have been captivated by the mystery of chemistry since age 8, and this man shares my sentiments. This lecture in particular brings the wonder and mystique of chemistry and atoms to the viewer beautifully. He's got it, and he shares it! Not one of my teachers of Ivy League professors can match him. Thanks.
I took chemistry in college a few years ago, I'm just watching this for fun... and I was like... why should I start at the beginning, this is gonna be boring. but I'm still learning new things! you rock!
omg that just blew my mind, THanks khan!
Hey do u have a video on tetrahedral structure diagrams?? If not it would be great if you could make one!! 😊😊😊 I rlly appreciate the work u do it has helped sooo much in understanding my nat 5 course work!!!!
I love you bro, you have no idea how much I look forward to these videos man!!! I spend hours at the library studying then come home and treat myself to hours of these videos. You are really helping humanity man! Thank you so much.
Its fascinating to listen to Sal talk, 17:50- end, he is so passionate and intelligent it blows my mind to listen too him describe concepts.
This may of just passed me my Science exam, thanks:D
U rock bro!
This blows my mind too :D Thank you I looove learning about these things!!
I love the drawings with different colors on the screen, that's very helpful and clear communication!
omg this video is so good i understand it better now:)
Maybe the free space in an atom is not really free, but is made up of stuff we can't see, like dark space or dark matter, or whatever.
Woah...
It's actually the Gluon Field.
Leia H So it's not nothing.
Parture Nope. Veritasium has a video on the Gluon Field. Nothingness, by definition, cannot exist. We wouldn't be able to detect it because it's not anything at all.
Leia H That which does not exist can't be detected because it doesn't exist.Just because you are not smart enough to detect things very small doesn't mean they don't exist. That would be the height of arrogance. e.g. dark matter and dark energy we know exist even though we can't see it. One scientist said we can see down to the 10 ^25 level, but we know that particles go down to the 10^125 level which we can't see but know exist. biblocality.com/forums
Thank You so much
I have watched many videos and not understood anything they were saying. You are the first person I actually understand
nice apple.... u just made me hungrier thx...
Are you still hungry 4 years later?
I'm here because I want to get an A in chemistry! :D This video was really helpful!
Did you got A in chemistry?
@@Mr__mehta
I guess she got D
@@bahaar5215 great it's not only me here after 7 years of this being online😂😂
I start chem in a few days, and I figured I should get an understanding before I go back to school. Thank you!
Brushing my basics! Thank you 😊
im 10 and learning about chemistry this is cool I wanna be a scientist ;D
Roblox_slayz XD wow that’s early I’m 12

thanks so much i was about to fail my test and this video helped me get an 83% thank you so much!
great concepts you have there, khan academy is now used all over my school, getting great results for tests, keep up the good work!
This should be watched before taking any chemistry course! Beautifully explained!
I'm just watching at home on my own time to understand chemistry better and so far I have learned and refreshed a lot. Can't wait to keep watching the playlist. 😁
17:40 - I love this guy, my mind is blown.
Very well explained!!!
you are extremely knowledgeable... thanks for sharing your profound understanding of all things science.
Your video is very informative for me.i like it.i also want to share my knowledge regarding chemistry with every one.
19:08-19:30 That moment when your mind gets blown
"Introduction to the atom"
epic title.
im so happy that u finally have chem vids up!!!
that was really cool and helpful. thank you!
You have an affinity for incomplete sentences followed promptly by compound-complex sentences and fragmented thoughts. I am sure these are just reflections of your enthusiasm but they must hinder the student who is trying to grasp one concept at a time. Even when I was teaching post-doctoral students, I tried to be both precise and concise at all times.
Good for you, asshat. Now you spend your time critiquing other people's youtube videos? That is a great use of an expensive education. Your parents must be proud.
davejss
Thank you for your kind words. Unfortunately, my parents have both died and I still feel the loss every day. Yes, they were very proud of me, as I was of them.
@ wholeNwon So...move on then. It must be hard being you.
i just punched my wall and it was pretty solid
I really enjoyed, thank you very much!!! This is a channel which I look for
Some pretty interesting stuff here. Thank you, Khan Academy!
Don't read the comments rather watch the video carefully.
Wow. Amazing stuff. Thanks. I thought this life was real. This is all an illusion.
Wow, was that good. I have watched his videos for 4 years on many subjects and they all leave me with a wealth of information I can understand. In this segment, I like the way he flirted with some deeper mechanics of the atom. You don’t get to 7.1M subscribers by not being terrific. Thanks.
Dude, your video is awesome!
Thank you!
OMG! It's that small!?
It's that small that u can't cut it by a sharp knife 😂😂😂😂
That’s what she sai-
oh, just to say I love u ~
Trying to hijack an educational video.
I think this guys videos are great, I intend to go through all the chemistry and bio material for a review.
Just began reading The Making of the Atomic Bomb by Richard Rhodes and this video really helped me wrap my head around what an atom is. I'm hooked.
If i'm bad at math, am i going to suck at chemistry or have a hard time?
If you have knowledge of basic math concepts, than you will be ok in introductory chem.
What if it turned out that we are mostly composed of dark matter :D
The ground. :D
I believe we are. I believe space is dark matter/energy and we are made up almost entirely of space. I also have a sneaking suspicion that there is only a correlation between mass and gravity and that gravitational fields are actually created by the displacement of space (dark matter/energy) by matter. I think dark matter is the building blocks of the sub-atomic particles we can actually detect. But what do I know, I just pulled all this out of my ass.
Justin Knight xi:nnythhhbh
***** you're thinking of dark energy
*****
That's dark energy
I can't show you my gratitude for posting this awesome video......my chemistry teacher is no match for you... I love your lectures but I wish I could ask some questions........THANKS
Thank you for making Chemistry interesting and simple-ish. =)
If 99.9% of an atom is empty space why doesn t metallic elements absorb water ?
Absorbtion has nothing to do with the space between atoms but how the various elements and there electrons react to one another. Keep in mind that you are in fact 99.9 free space as well...but on a atomic level that is so small that only radiation and a few other things can make it through.
because theres atoms
oh
@khanacademy thanks for all your videos and the unbelievable work you put it.they greatly help me self teach.thanks again( uk london )
Wow
That's definitely the best lecture I've ever payed attention to :). Definitely reminded me of a lot of "stuff".
Thanks Sal!
2019 education
2021🥲
Ok so i hold let's say a rock if most of a atom is made up of free space then what is the solidity i am feeling?
*****
Ok thank you that makes sense
And that also basically means you can't "touch" anything
+Danny Parker hey I was just wondering that If you are so smart! why were. you watching a simple video like this one?
+Danny Parker ever heard of pchem, biophysics, etc?
lol stuckup
wow this is amazing, you explain it very well khan!
Awesome Video! Helped Out So Much!
as you go deeper and deeper into physics and chemistry you just find out that whole of science is based on "APPLE"
Nope. Don't watch Ted.
in response to the other comments, This is a learning opportunity for alot of people and I appreciate the availability of these lessons and find it disturbing people feel the need to complain about free education.
Your description of orbitals was amazing
Too verbose! Fell asleep!
he is knowlegable..but a bad lecturer..too many repeates and uhh uhh uhh
Amerikajin91 so so so
Amerikajin91 I mean it’s easy to understand him even with the repeats and uhhs. He isn’t a bad lecturer
Amerikajin91 you can still understand him tho...
Amerikajin91 I agree actually
If you have the guts in your butt. You give this lecture
Awesome stuff!!! Thanks!!
I love the way you teach!
WOW. I love chemistry now. I really don't like it before but i love it more.
Well done, man. Very informative.
Thanks.
I applaud her...It's more intellectually beneficial then doing something else like reading a holy book...
Khan Academy simply rocks!Thank you.
you did a great job sir, i get it now! thx
Verry interesting and soo simply understand soo thanks my lovely teacher 🤗
Oh my thts really too much phillosophy & it really blew my mind
thankyou!!! u i acctually understand!!!
Wow thanks sal i didn't know you did vids on chemistry :)
