Chemistry on Khan Academy: Did you know that everything is made out of chemicals? Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
For free. For everyone. Forever. #YouCanLearnAnything

Rehearsing and having notes would help a lot.
Nice explanation of the Rutherford-Marsden-Geiger Experiment. Nice effort by Khan Academy on teaching kids science at their homes and free.
Now I know why Rutherford had thought the particles would just go straight through the foil!
Tissue paper and bullet reference was Epic 😊
90% of the people in the comment section are only worried or angry because of the person speaking. Who gives a s**t! Her explanation is acceptable. Good video!
Majd Akkari No it isn't it's as if she hasn't rehearsed once
Wonderful emphasis on the scientific method through it
I like the change of voice. I like Sal but who cares. The more the merrier. :)
I like that attitude, you're right!
I agree, she's doing fine, listen to what she's saying... this is how we move to new concepts of the universe. Who would have ever thought of "dark matter"...but now here we are looking for ways to prove it, 50 years from now well all be ok with Dark Matter and someone will find something else that doesn't do what we expect so someone will as that question and do an experiment that shows that our view of the universe was wrong. And on it goes.
Thank you very much for an amazing lesson. :).
But alpha particles are known as particles that you can easily block with just a piece of paper. So in this case how could alpha particles beam through the gold foil?
A piece of paper is very thick as compared to gold foil which is only a few atoms thick
I think this is a great lesson, thanks.
Amazing one.. liked it
you really described well
thnx a lot.
Very good!
Thank you!
Great Video!
Awesome ❤
This is Interesting
your voice is so cuuuuuuuuuuuute
Is there ever a person who hates deserts? I think maybe plums, but even triple chocolate cookies? Oh the humanity!!
+daedra40
Probably nomads carrying triple chocolate desserts hate deserts, with all the heat and the melting and such
markgriz You know, I was actually very wary about whether it should have been one 's' or two to differentiate between the sands and the heat, and something like a yummy triple chocolate dessert xD
Some say spelling is hard, and in times like these I concede defeat to the powers of the alphabets!
Omg, I love ur voice!!! And ur explanation was understandable!!
Viewers may also visit 'Learner's Console ' for this chapter too 🙏
I will try to do the experiment again.
Cool beans.
The gold foil is 1000 atom thick then how this heavy alpha particle pass through it.. please any one know about the structure of gold atom arrangements in the foil.
Back up for Sal maybe
Sal please, this is your channel. Keep it that way.
she sounds so cute
Hey, I love you.
9:44
Empty Space?
Vaccum
man i sure do miss sal... sorry and no offense to you
4th
we want Sal back, please
I appreciate her effort. But as you can see, i dont think im the only one who prefers Sal explaining. Sorry dude.. but i couldnt really focus on what she was saying.
3rd
1/12000 reflected not 20000, it matters a lot
TRENDS GO 1 in every 20000
knock knock
is your profile picture no-face from spiriting away?
Who the hell is this?? What have you done with Sal?????
+curryeater259 Nothing, I'm here man.
There IS a God! Thanks to him/her, you just have better teaching chops, that's all. She's not really bad, just not you and not experienced or polished enough to keep our attention for long. Which in fairness COULD be our problem, but it's easier to say you're better!!
2nd
Alberto Rivera you are actually first
maybe sal's wife ?
JMPC here 🤣
Who is talking?
+Richard Fry Sal Khan and another person
Bryan Nguyen What is her name?
Richard Fry I am going to email him :)
Bryan Nguyen did you find out
Yaa
So, where are the electrons?
+iiperento You can't define where electrons are. There are probabilistic models that state the most likely position an electron could occupy in an atom
***** I could probably answer my own question if I know more physics. Thanks anyway :D
iiperento Haha no problem :)
Rutherford was a kiwi, not a brit
She has a cute voice.
WHO IS THIS WOMAN WHERE IS SAL WE WANT SAL
Was a good video apart from, ''He was was a thorough chemist'. pls.
the absolute amount she messes up
OMFG WHO IS THIS I WANT THE OTHER GUY BACK NO KHAN ACADEMY I WANT THE GUY FROM 201Q NOT YOU
I gather you're a little upset! Kind of funny not for the poor girl teaching but, you know..... We all like Sal obviously but we should be nice, this girl has to start sometime. I agree with you but she really tried and we aren't helping her to grow this way. She WAS trying to help us grow after all, we should be respectful to her, please, thank you!
21kpatriot okay buddy
Asa Jaman
You're a good person!
21kpatriot Thank you buddy!
I can't learn anything listening to this female's voice. Too many pauses mid-sentence and she repeats herself, very annoying.
That is exactly what Sal does.
