How did we get here? Well, in terms of Atomic Chemistry, Hank takes us on a tour of the folks that were part of the long chain of other folks who helped us get to these deeper understandings of the world. From Leucippus to Heisenberg to you - yes, YOU - the story of Atomic Chemistry is all wibbly-wobbly... and amazing.

@michellesullano2069 6 лет назад

Thank you so much for a great presentation!! first major discovery that set off modern atomic theory was that atoms aren't in fact the smallest things that exist. J. J. Thompson discovered the electron in 1897, which led him to posit a “plum pudding” model .

@ricardoperedo3517 10 лет назад

This is so weird. I was doing some Chemistry homework on the Atomic Theory, and I got inspired to watch some "Crash Course: Chemistry" videos. So I opened up the RU-vid channel, and the first thing I see, is this video. Awesome! Thanks Crash Course for all your videos. I really like watching these videos so I hope you keep it up with the video, I'm also looking forward to watching future series. Thank you, and have a nice day!

@dajiahshai 4 года назад

@nymphedre2626 5 лет назад

oh my god, i just discovered this channel and I’m soooooo happy. My chemistry teacher is really good, but u have a completely different way of explaining things, it’s almost like I’m not studying. Thank u soooo much for those videos, u r amaaazing!! (if there r some mistakes, sorry, I’m from Poland)

I am studying chemistry at the moment and i was taught that the cathode rays weighed about 1/2000 of a hydrogen atom instead of arround 1/1000

@mikekelso138 7 лет назад

I think Thomson's methods of measuring the mass so many years ago were not very accurate - so his estimate of 1/1000 x an H atom was not so bad, considering. But you are right, electrons are approx. 1/1800 x an H atom.

@calinottingham3351 7 лет назад

There's probably a good amount of different numbers, probably in between 1/1000-1/2000, but I'm not sure so don't quote me on that

@synth2141 6 лет назад

You are right I know I'm 4 years late and many others have answered but yes J.J's first measurement WAS 1/1000 but later chemist corrected the measurement to about 1/1840ish kind of disappointed hank didn't correct it but oh well I doubt it would end you on a test unless it's very specific but still
