- 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.

Now we won’t fail chemistry 🗿
who else has a chem test coming up
tmr
Me!
tomorrow
Same
lmao I didn’t pass mine
Teeny tiny correction for y'all! At 8:50, we misspelled "Heisenberg" as "Heisenburg." Sorry for the mistake!
My chemistry teacher if you are reading this please resign
lmaoo
Lol what I feel about my teacher
My chemistry teacher used this
I'd be happy if mine just played these videos and tested us on it.
I second this
if this guy was my chemistry teacher I'd be getting amazing grades
yes
+MODERN MUSE I wish!!
+MODERN MUSE Your chemistry teacher would have time to put together awesome presentations like this. Mostly because your chemistry teacher wouldn't have the production staff and kick butt animators.
WORD11
OMG same! My teachers name is legit Mr stoner
Whos watching this in quarantine 2020 becuase school dont help that well
I need this dude as my chem teacher, I'll be getting grades higher than Jin's confidence in his looks
Yup and that's my co-Army right there💜💜💜💜
yep. you really do man.
@@howelsimos2088 and that's my co-coArmy right there
same
the way i had the exact same thoughts while watching the video... armys really do share brain cells
Einstein just steals Bohr's tea at 5:45 WTF Einstein
Jajamola888 I guess Einstein was bohr-ed... GET IT?!
K i go now
+Tanishq Desai noicce
YEA!!! :O
That's so savage. He can afford tea. GO GET YE OWN TEA EINSTEIN
See my surname
Raise your hand if you came here for the science assignment.
For myself:
2:15
3:13 JJ Thompson
4:21
5:31-planetary model
name is actually spelled JJ Thomson
I've already learned all of this but this does help me review and it's interesting to watch the history of the Atom especially with the elegantly animated graphics
LOL EVERYONE HERE FOR CHEMISTRY WHILE IM STILL WONDERING WHY THIS IS IN OUR PHYSICS LIKE WTF
I love this episode! I have always liked 'the history of things' like this. It's not atomic chemistry its the history, the story of how we went from A to B to C to D and finally F.
JOHN Dalton, not JAMES Dalton
2:15
Joe Zhang Lol XD
james is a nickname
Glad I'm not the only one XD
It might've been a Harry Potter "James Potter" joke
you don't get the joke xD
I need this guy as my teacher, my teacher only sits on her desk and reads what’s on her PowerPoint
I love this episode. I always seem to get my science lessons as a series of conclusions with no clue how scientist arrived at these conclusions. I really appreciate this walk through how they developed the atomic model.
This might be an old video, but this saved me... BIG TIME! Thanks for the info! I learn more from Crash Course than my teacher at school!
+Isaac Lee Your teacher either sucks at teaching, or doesn't understand the material him/herself. Unfortunately this does not necessarily get better with college. It's a good thing you sought out other sources of educational material. Don't assume your teacher is a genius.
my teacher does suck....so true that
*than, I bet your english teacher sucks too.
alright.ill fix it lol. At least i see my mistake XD
wow... Hank went through all the names, experiments and mathematical concepts of atoms, which I learnt for the past 15 years, in less than 10 minutes... Very impressive..
Hey dude these videos are great for learning because you add humour but are still to the point, they help me understand better while learning at home
Amazing! Very informative and the illustrations were on point!! Keep up the good work Crash Course!!
it was very interesting to see the development of the atomic model! thanks for the video and keep up the amazing work!
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 UA-cam 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!
we watched this in science today, and I screamed Breaking Bad reference
this is amazing!! literally covered everything i need to know! thank u
I feel that if I watched every video this dude's produced I could graduate in no time. Like seriously, this guy's covered so much, I've been asked to watch his videos for class so many times. I probably know this guy better than some of my teachers and classmates.
You did not mention Schrondinger?????????????
His formula gave rise to those s p d f models
It was more Schrödinger than Heisenberg not even a mention?
***** Did daddy feel offended....??? I was just pointing out idiot
Rajit Roy Also no mention of Milikan, Chadwick or De Brogli? maybe the're just not as important.
I love a chemistry teacher teach like this. Plus his Save Ginny Shirt. HAHAHAHA
u mean gaaaaaaaaaaaaay shirt
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 .
What about James Chadwick and the discovery of the neutron?!
***** I wish I could however I don't have a job or money to do so
+Steph Berry Dis is tru
Steph Berry sssssh we don't talk about him
Exactly what i was wondering... Apparently its not important enough.
@Adriteyo Das different person
JAMES Chadwick cane after Bohr
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)
My science 8 class teacher gives a lot I mean a lot of cringey animated videos and this once he gave a video I could watch without cringing so good vid :)
The whole time I was watching this, I had your talk video in mind. I'm so lucky to get to choose my teachers!
exactly what I needed to end the day - thanks CC
thank you for summarizing an entire college chem reading that now I don't really have to do :)
This is great! I love all the animations. The only negative thing I have to say is he talks too quickly. I feel it would be hard to follow for someone who has no background knowledge of chemistry.
It's a crash course, it's meant to be a review rather than an introduction to an subject.
Try playing at slow playback speed
@@dinimasharma3549 thx for the tip! I just adjusted mine.
It’s so cool that people who lived such a long time ago can influence what we know today!
This actually really helped as a good review for my Chen class. Thanks!
2:16 that harry potter reference.
I wish he was mine
He is really divine
The hero who conquered the dark lord
He was probably pretty terrible in the bed.
You, my friend, are amazing, Thank you for helping me get through Year 11 and 12, or as Americans may call it, Junior and Senior year.
+Reuben Wallace-Gibb (Spirit of Harmony)
Lol
keep up the fast work. More info in less time love it
This really helped in my chemistry assignment fam, thanks alot m11
Crash Course Biology > Crash Course Chemistry > Crash Course Physics > Crash Course Mathematics > Crash Course Formal Logic > Crash Course Philosophy > ???
Theology?
Also, we need John to make Crash Course Economics, Crash Course Sociology and Crash Course Psychology, to close the gap at the other side of the spectrum.
Your prediction was close
TapOnX and law
This was made 3 years ago and we're just about to learn about this in class
bless this video im in junior high (my last year) and we're learning about atomic theory and the different models
Helped me a ton! Thanks!
Hmm.... Wasn't it more Shrodinger's theory who predicted electron probability densities, nodes, etc., while building off of Hiesenberg's uncertainty principle (excuse the spelling on their names if I'm wrong, by the way...)
Anyone here from Ms. Perez’s class?
P.S.: Ms. Perez if you’re reading this, hi, hope you’re having a good day 👋🏼
!
wonderful ! with all these information i will be able to understand chemistry better
Wow! Loved the vid. thanks much!
What do you guys use for editing and animation?
his name was JOHN DALTON, you missed that but the rest is freaking cool
this vid helped me in chemistry test and I want to use these vids 4 my gcse, keep on doing it
Thanks this was good but also further confusing. I am studying Chemistry and Physics so we are crossing paths. Over all this really helps.
0:23 They developed it with the Pythagorean Theorem, Zeno's paradox and the Golden Ratio 😂😂😂
(A reference to AC Odyssey)
Good video overall though- atomic theory gets pretty awesome when you can apply its principles to like 6.02*10^23 atoms.
Overall very concise. Enjoyed it
Great video. Helped me loads! thanks!
Thank you soooooooo much.... this was sooooo damn helpful:):):)
it wasn't for me thats for sure :/
Hailey Jeong
Same 😂😂😂 he talks like rapper
And they explained too many sections in one video I think it’s too much
monisha elangeswaran u r mad u thanks him ..........
the vedic books are the oldest and even more advanced than today when it comes to science
"And cheese atoms are squishy and delicous"
best kind of learning EVERRRRRRR!!!! TQ so much for these great vids!! :)
Thank you. I can really use this to study for my test tomorrow
The mark... Are you....
Dalton : yes I am the goddamn Harry Potter !!!
Love your videos, unfortunately every time I try to share them with my students the majority of the class complains that you talk too fast. Everything is so well done, I wish they were more friendly for a wider audience.
your scripts are amazing! great job (y)
this is amazing thank you crash course!!!!!!!!!!!!!!
How come whenever they show a historical figure's face they color it like an oompa loompa
Halloween was yesterday, its November 1st, my family is blasting Christmas music, drinking eggnog, and dancing... the *FREAKING TREE IS ALREADY UP!!!!!!!!* >:C
Broken Strategy Clan oh my, your like tho only other recent comment here rn
I have a chem test tomorrow and this just HELPED ME A LOT
You made learning fun and easy! :)
"Hank is a mass of incandescent gas" (1:47) hahaha
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
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.
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
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
Ummm.. it's 1/1730
That's what has been taught in my class
Omg this really got me so excited!!! Yay physics
Thanks for posting this
Cheese particles :)
"I am the one who knocks" :D
I was taught that Rutherford expected most of the Alpha particles to be reflected because the plum pudding model implied that atoms were solid mass with negative charges dotted around. Anyone care to explain the confusion?
Test tomorrow. Time to binge watch these.
*In the Rutherford experiment, he didn't expect the alpha particles to go straight through. They were positive and so was the atom's emitted charge which means he expected them to repel. Them going straight through showed that there was a lot of empty space.*
manooooooo, já muito é muito complexo estudar química e ainda um vídeo em inglês e legenda em espanhol. Eu não sou fluente em nenhum dos dois idiomas, Please subtitles in Portuguese !!!
Finally something on the show that's easy to understand.
I gotta write a reviw on this video; thanks a lot, Mr. Delgado.
Literally learned more in this video than I did in my junior year chemistry class.
2:15 its John not James dalton (said it as James dalton)
yay go New Zealand. we make a huge breakthrough of chemistry
I LOVE YOU I LEARNED SO MANY😭❤
Love the somewhat subtle Breaking Bad reference
Breaking bad reference
i have to take notes on this *UGH*
Awesome work!
7:58 Super Mario bros reference!
What school do you teach in?! I am willing to move!
He is an actor
WTF, he has a B.S. in Biochemistry
you have shown that in thompson experiment the electrons are in random motion but in all books and websites i visited, they have mentioned that he proposed the electrons and protons are at rest.
Thank you so much this literally saved me I didn't understand it at all at school
Yo, Mr. White!!
Hello, past humans
I am from the distant future, I saw this video in the archives and wanted to tell you that there have been new discoveries in my times. Since 2057, we know that atoms actually consist of 8 different types of particles. Good luck
there are more than 8 kinds of particles in atoms and we've known that for like 40 years mr time traveller :)
+kotzzz9 name them
+Oogie Boogie 6 types of quarks
leptons gluons muons electon neutrino tau photon and then there are also the 3 (?)bosons and there are more of them but they exist temporarily
+kotzzz9 would you like me to look up in the archives when the world ended?
+Oogie Boogie yeah man that'd be cool
Would have been great if you would have mentioned Chadwick discovering neutrons. pretty good video anyhow
I think this would have been a great introductory episode.
When James Dalton=John Dalton ? hahah
That is a nice jacket.
Daniel Arbiter ikr XD
this is way more simple and quick than the vid we were assigned to watch
