This video is about the different ways that scientists have pictured the atoms over the years. It starts with Democritus and Leucippus, the first philosophers to discuss atoms. Then John Dalton did experiments on atomic theory. J.J. Thompson proposed the plum pudding model of the atom when he discovered electrons, and Ernest Rutherford countered with the nuclear atom when he discovered the nucleus in the gold foil experiment. Niels Bohr imagined that electrons circled the nucleus in orbits, and Erwin Schrodinger's quantum mechanical model pictures electrons buzzing around in orbitals.
time stamps:
0:19- Democritus (Greek Model)
2:43- John Dalton (Dalton's Model)
3:43- J. J. Thomson ("Plum Puddling" Model and Discovery of Electrons)
5:10- Ernest Rutherford (Nuclear Model and Discovery of Protons)
6:08- Niels Bohr (Bohr Model)
7:00- Erwin Schrödinger (Electron Cloud/Quantum Mechanical Model)
8:38- James Chadwick (Discovery of Neutrons)
Thanks
Bro you saved me from my notes ty
No Heisenberg :(

I'm a chemistry teacher... Your explanation is far more better than what I was taught and what I've been teaching my students... I learned!!
Finally a responsible teacher who accepts and improves.... Wish everyone were like you sir 🙁
I love how to talk at a good pace! Your videos are so much better then crash course, he talks so fast I can't process what I'm hearing.
SOOOOOO TRUE MAN!!!!!!!!
I feel, crash course is way to fast, i like to take the time to listen like tyler.
crash course is not an educational channel.
um... yes it is. Of course it is. Maybe you don't like it as much but it is very VERY clearly and educational channel.
Esete Tena hi
Esete Tena Yes,I used to open a sub to read!
No lie bro you nailed it with your explanation in videos like these. This talent is yours and God knows you make life for
others a lot easier
Trap Lungu yasss
Yes he does!
Throw Back when I has chemistry in high school and this guy taught me more than my teacher ever did
when your teacher sends you to watch a 10 min vid smh
lol same
Its worth it tho
me rn
Same
Sameee
whos teacher send u here in 2020 bc of zoom smh
Same smh
Yeeep
mhm

Tyler! Tyler! Tyler...I'm 45 yrs old and going back to vocational school. Started reading my books and overwhelmed even while reminding myself it's the first read of many before I start to absorb information. I never even took Biology and here I am in Anatomy/Physiology at once. Thank you for your videos. Your gift of teaching is so appreciated. Who would of thought how much we can learn through this "internet" stuff. Thanks again! :-)
My teacher made us look this up 😒😒 but good video i like how you explain everything👍
Same lol

Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
I think every teacher should give an introduction like trivia, history, etc to almost any subjects before the class begin. Just like what you said about Democritus, somehow it pumped me up a little bit more, to learn and to appreciate science.
same I am in 11th grade (I don't live in USA)
I've been learning about atoms at school for 3-4 years and never heard of Democritus.
Chemistry is now more interesting for me.
Your videos are always so organized and creative. Thank you so much, I have truly learned alot
.
I love the way you explain. It's at a moderate pace and the diagrams and written information is so helpful while learning. Thank you for spending your time on doing this!! This has helped me so much!!
I actually hope you're having the best day ever and that your life is going amazingly because you literally saved mine almost a whole decade in advance when you posted this
Best explanation of the atomic models I’ve seen so far! Great content!
Amazing videos, I learned too much things from your videos. You teach us in acreatie way, I feel like I couldn't understand anything in chemistry except after using your drawings and your awesome way of teaching. Thank you again and I have a request on videos about the " Energy Levels, and Sublevels in Atoms " and " Electron Orbit and Atomic Orbitals " and what contain the other, because I really got confused with those 4 terms
literally this channel is the only helpful and understandable one for me when I'm learning chem
U made our subjects easy , up to some extent!😊 Thank u!
This channel is pure golden nuggets! Very clear, step-by-step and visual way of explanation ! Awesome !
Love your videos, don’t love how you use the word “lying” at the end, only in the context of recent trending spike of antagonism against science, especially online/on this platform especially. You’re not lying, you’re simplifying for the purpose of understanding, which is utterly acceptable, and I appreciate, because an understanding of chemistry never came to me as easily as an understanding of other sciences.
On another note, your explanation of the schrodinger model has left me with a lot of questions, in particular regarding absolute states of electrons when charged by photons (I came here from a series of videos trying to explain spectroscopy, in case that gives some context), but I evidently need to watch a little more before knowing the right questions to ask about either subject. Do you have a website that best describes which order to watch your videos? Is it just the order you uploaded them on UA-cam? I’m starting to watch your playlists, but they seem to go back and forth in terms of level of understanding
Back in my day: "Wow, you are such a good teacher. You teach all the things so elegantly. I love your teaching methods."
Couple years later: "I am here because tomorrow's my chemistry exam. And this is helping me so much. Thank you"
Today:
"My teacher sent me here because zoom, online" (And shaking their head for some reason)
aye thx for helping me fill out 70% of my chem hw
Tyler Dewitt, you are the best. I never met or heard anyone who would explain the complicated enough things so logically, clearly and entertaining. I wish somebody thought me chemistry/physics like that earlier. But better later than never. Great job! Thank you.
I never knew that electrons buzzed around the atom like how you explained in the Quantum Mechanic Model! Very good explanation of how the electrons worked!
Fantastic Tyler..great insights. and protocol (videos)
I vaguely remember... some of these concepts... The Bohr model was used in the classes I took to explain atoms, except I've been led to believe that's how atoms work and this is the first time I've seen orbitals at all (at least, I *think*... the material was difficult enough to learn already, even if I _did_ have an awesome science teacher).
So thanks for clearing that up for me, like, ten years later. :P Will happily watch the rest of this series.
Dude awesome videos! Very well presented! Keep it going
For my presentation tomorrow! Thanks Tyler!
I Learned so much from your videos. I knew nothing regarding gas laws and it's formulas but I watched your videos and felt comfortable hours later taking the test!! Thank you for your videos...I learned so much within the short time I watched the videos than the three weeks in lecture! Sadly, I cannot access the website! Thanks again so much!
OMG! I really have no idea how I passed chemistry before these divine videos were made !!
In love with his videos.. precise teaching and c'mon - I can't be the only one watching his videos right before a test
This is my absolute favouite video on UA-cam. Thank you for a stunning explanation.
amazing presentation it helps a lot thank you sooooo much
You're seriously the best. Thank you for the videos. I wish there were more teachers like you
Love the way you explain! I always use your videos as topic introduction. Thanks!
You're literally the best teacher ever!
This is great! I actually understood well. Appreciate you efforts. Keep going.
this is great! i actually understood this well
thank you
WHY DID HE SAY THANK YOU IM CRYING
Excellent way to make understanding of the concept in a very clear method.👍Kindly also post bohr's model and its applications..
Thank you so much! You've made this sound so simple yet very informative!
How is life now
I like the way you speak and explain the complex things in easiest way....
I love your videos so much they're incredibly helpful and have saved me
internet is a gr8 blessing coz of few teachers lyk u!
in love wid ur video...
your videos are amazing dude!!!
Thank you for explaining the concept well! The many different kinds of atom models are very fascinating and helpful to know. The topic now makes more sense to me thanks to you. This refreshed my mind about the different models of atoms.
I am so thankful for your videos, they are excellent!
However, I have a request on a video about the equilibrium concept, as this is something I (as well as several others in my class) find difficult, and none of our teachers have so far been able to give us a good definition!
this is the 6th video I watched about atoms history and this is totally the best one.
I left my book in school for the summer holidays so this really helped me with my homework
Thanks
One of the best demonstratons I have ever seen
How excellent description of you
THANK YOU SO MUCH
This video can help me a lot (Y)
Just Awesome explanation. Watched & Subscribed.
Thank you for this video, I've been searching a good explanation of orbitals and I just wasn't able to find It until now.
this really helped a lot, thanks :3
U r highly creative and makes complicated things into simple fragments!! :)
We got told to write out the timeline of atoms, my teacher gave us videos but it wasn't very helpful... But then I found this video, I love how you explain things and this was very helpful! :D
thank you so much for this video
I have just watched some of your videos these are really much helpfull i have been fallen in so deep with you brilliant creative ideas these gonna help me teach my kids too and cleared my all previous concept .
Thanks for making this video. I liked it very much. you're a legend.
Your a wonderful teacher. Do you have any video feeds for determining acid and bases pH, pOH, [OH-], [H3O+], concentration and dilution calculations, and stoichiometry applications?
You are truly the best chemistry teacher... Plz make more videos
Thank you so much sir !
It's the greatest explanation for atomic structures on UA-cam.
Thank you so much. I love your videos, you're just so talented at explaining things :)
can u please upload the videos of all the part???
omg! i just got it.. read my book like.. a 100 times and still couldn't get it caz , its hard to understand when u cant picture what they are trying to say! but u dd a great job with the whole thing!! i have a test tmr and THANK YOU!
I gotta appreciate you sir for your hardwork and dedication
this whiteboard thing you've got going on is genius. i watched all the VESPR videos. your style makes it easy. i'm going to stick around and soak up everything else
Trust me watching this at 1.25 speed works a lot. It feels pretty regular and time went flying
Thank u so much 😭
Fantastic series...thank you!
tnx for this video... i am now ready to take the exam!!! 😀😀😀
You are life saver for my 13 year-old daughter. You made the hard to understand concept so easy! Thank you!
keep making more please and thank you
Man, I love your videos.
You Help me a Lot with ma Chemistry ! :) Thank u a lot :)
Thank you for making it easy. Thanks Tyler!
then which is correct bhor's one or quantum mechanical one?
Cool explanationsss!
You helped me on my HW thank you!!!!👍👍👍👍
very helpful video for my atomic theory timeline homework
This lecture is awesome! Thank you so much, I now understand the difference between
The Bohr and Quantum models :)
You are Lucky Elisa because your syllabus include Quantum models. Now I'm in 12th class (India, state Maharashtra) But There is no mentioned any Quantum model in our entire syllabus. I know about this Quantum model right now because of Tyler Dewitt sir.
Akshay Parulekar but cbse has quantum mechanical model topic in class 11 only???....
gunjan sharma I've not cbse, I've Maharashtra Board. Now I've passed those exams. Now I'm learning Computer Science. I'm studying in First Year Computer Science.
oh i see
How’s it going now
Wow, my teacher gave us an assignment for different structure of atoms and the only place where I truely understand is a 7 year old video. This is just amazing, great video 👏👏
Loved the video man :D!
Thanks for posting this
Thank you Sir for this wonderful presentation that u made.. I will apply this to my students later.😊😊
I do love how visual this video was.
anyone can learn chemistry very easily by these videos ...
I want to say only that thank you SIR..
thank God for this man. I spent 45 min trying to understand my first lecture of chemistry at uni and was definitely not interested and did not understand what my teacher was saying. In less than 15 min, he nailed it and I understood.
Love your videos !!! Amazing job :D
sir where is dicovery of proton and bohr's model
Could you make a video about the s, p, d, and f orbitals, please? Thank you do much for your videos!
Such a great video tyler. You taught me more in 10 min then my science teacher has all year! Very good job man keep it up!!
Tysm it’s currently 11:00 and cramming for my chem test!!! 😭
The best teacher ever i LOVED your teaching
You can add a bit of background music so it is soothing for the brain while understanding the topic that you are teaching.
Great video. But one fact i wish you included in the video is that according to Quantum mechanics theory of atomic model , The electrons are not buzzing around like flies drawing those shapes, instead they are more like wave form and have an area of probability where the electron lies. when disturbed the electrons behaves like a particle , when undisturbed electrons behaves like a wave . That dual form of electron is what created curiosity and pushed scientists to experiment and think about adopting atomic model based on quantum mechanics theory which accommodates wave form .
PS : this is my understanding about atomic model by reading articles and watching many videos.
Ah! you did a great job of explaining it and absolutely clearing it up in a neatly and well presented way. Thank you!
thx really helped me with my 8th grade science on atomic model timeline project
do you have videos on quantum numbers?
wow, great video. really helps me to teach my students;)
I've used the Bohr model a lot in chemistry.
Thank you bro! You helped me write my chemistry essay.
