About Atomic School:
Atomic School supports the teaching of Atomic Theory to primary school & science students .
We provide lesson plans, hands-on classroom resources, demonstration equipment, quizzes and a Teacher's Manual to primary school teachers. Animated videos that clearly explain the scientific ideas supports learning by both teachers and students. As a teacher, you don't have to look anywhere else to implement this program.
Our work has been verified by science education researchers at the University of Southern Queensland, Dr Jenny Donovan and Dr Carole Haeusler, who confirm that primary students are capable of learning much more complex scientific concepts than previously thought, and crucially, that they love it. Students run to class!
The program has been trialed in Australian schools as well as schools in the Philippines, Iran and India. It is conducted as holiday workshops at the Australian Nuclear Science and Technology Organisation, the Queensland Museum as well as the World Science Festival.
It has attracted wide media interest, including TV, radio and print, and the research data has been presented at prestigious American Education Research Association and Australian Science Education Research Association conferences.
Atomic Theory underlies all the other sciences- genetics, electronics, nanotechnology, engineering and astronomy- so an early understanding will set them up for a more successful learning sequence for all their science subjects, and support their mastery of mathematics as well. We also have extension programs that cover Biology, Physics and Astronomy to an equal depth.
About Ian Stuart (Email: ian.douglas.stuart@gmail.com):
The founder of Atomic School, Ian Stuart, taught Chemistry and Physics for 25 years at senior levels before he realized that his 8-year old son, Tom, could understand Atomic Theory at a much deeper level than he expected. After visiting Tom's class at school, he discovered that his peers could also grasp the abstract scientific concepts, as well as apply it usefully to the real world.
Ian then developed a program to teach the advanced concepts of high school Chemistry, Physics and Biology to students 10 years younger than they normally would. He found that this engaged their interest in modern science early, and sustained it through to high school and beyond. It also sets them up for future success in their academic and career paths.
Ian has a Bachelor's Degree in Chemistry from the University of Queensland and a Master's degree in Electrochemistry from the University of Melbourne.

Video transcript:
Very helpful video. Speaks slowly and clearly with good pausing. Thanks.
Thanks, this is going to help me in my chemistry exam. Wish me luck! 😁
The reactivity of an element is based on, like he mentioned, its number of electrons per shell and the capacity of each shell. If all the spaces in a shell are not filled, an element is reactive because it is necessary for all the "slots" to be filled. For instance, hydrogen has 1 out of two electrons in its shell, and oxygen has 6 out of 8 elements in its outer shell. Two hydrogen atoms can bond with an oxygen atom to form water. This happens because the two electrons in hydrogen atoms give the oxygen atom more stability with 8/8 electrons, two being from hydrogen atoms. This also means that one electron is distributed from the oxygen to the hydrogen, causing two out of two electrons in each hydrogen atom. This is the basis for most reactions.
OMGosh! so good! I get it now - THANK YOU.
This video was incredibly useful and easy to understand!
Excellent and extraordinary video as all that I have seen so far created by this great master professor. Thanks so much Ian Stuart for teaching me and for you passion for knowledge! I can't wait to see which video is next! Julián Gómez Giraldo.
I hate the music, but the videos are very informative
Same!
Thanks to Ian Stuart! I've watched a lot of your vids. You have a very effective phrasing to explain some very difficult topics for the Human mind to comprehend. Your videos have helped me actually comprehend things that I have known for years. Being able to "know" facts by rote is far short of true "Comprehension". Thanks again!
very much useful &easy to learn
Excellent video. Very well explained. 👍
Awesome video! Concise, brief and to the point.
Your explanation is fantastic!! Thanks
But sometimes scientists write 2,1.........................................We're on a roll here
I'm confused:
If the outer most shell of an atom must first fill up with the maximum number of electrons that that shell can hold (ie: 3rd shell can hold a max of 18 electrons), then why is it that once you progress past the 3rd period (row) of the table, some atoms fill the second outermost shell with only 8 electrons, then proceed to start compiling electrons onto a subsequent shell?
For example, Potassium (K): with a total of 19 electrons, that should require 3 shells, however K has 4 shells, with 2,8,8,1 respectively. Shouldn't the spread be 2,8,9?
Sorry if this seems like a dumb question, I'm just trying to understand this
Actually, the formation is just 2,8,8,8,8,8,8,8,8,8,8,8,8 and on and on and on and i
Debashish Mukherjee not if you look at the periodic table it's not... starting the the transition metals, the shells begin to exceed 8 electrons
+whostolemyTV Hello, I hope I am not too late to reply, but the formula of two n square we use to figure out the electron formation is only accurate up to the 18th element. You might already know this, but each shell has orbitals, or sub-shells, whatever you can call it. The first shell has 1 orbital called p, 2nd one has s and p, 3rd one has s, p and d, fourth one has s, p, d and f, and all the rest have four orbitals. Now, the electrons usually are accommodated in the shell that costs them less energy, and there is a formation that would be hard to describe through a comment, however, the electrons usually fill up the orbitals. The sequence of the orbitals they would fill up would be:
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s etc
Where 1 represents the number of shell and s,p,d are orbitals.
So, orbitals have different capacities. s orbitals can hold 2, p orbitals hold 6, d orbitals hold ten and f orbitals hold 14.
This can get confusing, but here's an example. Iron (Fe) has 26 electrons. So, the formation of it will be:
1s2. 2s2, 2p6, 3s2, 3p6, 4s2, 3d6.
So if you add up:
The first shell will have: 2
second shell will have: 2s=2 2p=6, so the second shell will hold: 2+6=8
the third will have: 3s2=2, 3p6= 6, 3d6=6 or, 6+6+2= 14
and the fourth will hold 2.
There are exceptions to this too, like copper and chromium.
I'm sorry if I have only confused you further, and if you already knew about it.... well then just ignore it, I guess?
anonymous haha no problem, yea Ill be taking chemistry next year again so I'm sure that that will brush up my knowledge. I'll do some self educating during the summer to prepare as well, but thanks!
This is the best video I have every seen on this topic. Thank you so much for explaining the things so nicely.
Very helpful to explain electronic configuration of atom .
How come the 3rd element and up no longer need the neutrons to cancel out the protron?
Very educational! Tx for uploading!
thank you this will help me for my exam + i am forced to watch this
Really helpful stuff Ian, I study Energy and Environmental Engineering, so videos like these are quite handy for going over the basics, thanks,
Andrew.
you dont know how much you are saving my ass right now thank you so much :D
thanks very much
thank you this help me for my 105 items exam
Tonns of thanks LAN Stuart. Amazing, helped a lot to recap my science understanding.
whats making the electrons spinning around the protons? the quarks inside the protons?
Wow! Now I understand!
it is really helpful ,thank you
exam tomorrow thanks for this!😊
theme music reminds me of Breaking Bad....seriously!!
I like you
so what's the shell made of? Or is the shell only the orbit path?
+Ian Stuart First of all many thx for your response. Love physics but didn't study at uni level sadly, so have a deficit. Nature is certainly difficult to grasp in some areas (I'm still dissatisfied with all the theories regarding gravity, but that's another subject).
Of course when you say "shell" it is natural to think of it at first as a "thing" as you say. So OK, that's cleared up. I presume we can assume that no matter what we're dealing with there is always the movement in the orbit (constituting a shell) and that the energy levels remain the same for the respective orbits, i.e. the first shell/orbit energy level maintains the "first orbit" and the "extra electron into the next shell" is maintained via a stronger energy level in that "extra" orbit which is effectively further away from the proton. Much like two non-geosynchronous satellites i.e revolving around with one being in a low earth orbit, and the other in a higher orbit in those respective orbits by the differing energy levels you mentioned.
If only one could really grasp what energy is in that context and how it is a force, less any components, to manage to accurately hold those levels/orbits. Enjoying your videos & subscribed. Many thanks.
thanks for making such videos I appreciate it from my heart Good Job
Thanks Ajun
I just love this video. My concept about nuclear force got cleared now. Thanku... And the music break was awesome.. I wish We all study chemistry like that.. 😍😍😍😍 just subscribed..
simple and easy to understand
love it!
wow!! Thank you so much for creating and uploading this video! You have a gift for teaching!! Thank you!!! God Bless you. =)
"they are really cool words to learn" hahahaha. But you did hel me out thx :D
+GREENKAV yeah i cant spell help
thx so much
excellent and extraordinary video.I like it:)
He just basically explains how we generationally set our DNA pattern thru the way we live.
Wow, this is clear and concise. I'm posting to my kids facebook page!
I love it!
Thanks for the easy to understand video of how atoms work, that was useful, please post more especially about quantum particles such as quarks etc.....!
Good for Stage 5 CW. Basic Introduction to Atoms and how they differ. Starts with H and builds them up slowly.
Mr. Stuart- I want to know if I can request permission to use your videos to teach in my classes? Your videos are wonderful and I want to share them with the kids.
oh thankyou thankyou thankyou thankyou that was amazing so helpful
Are all the electrons revolving in one plane or in different planes, and if so what are the angles among different planes of orbits? If electrons or protons are made of a matter named as quark, what are the properties of quark? Its unit weight, volume, are the quarks further divisible?
very useful ! like it amazing
Thank you a lot Ian Stuart! Great job, you've made me understand the atomic structure the easiest way! Great job and keep it up!
This was actually done well.
clearly understood sir!
U saved my science mock GCSE's, thanks
Thanks for the video! I am wondering what are the rules for the number of neutrons in the atoms, it only shown up once in He atoms and then disappeared...
It make sense now, thanks for the great insight! I am on this right now :)
I'm so thankful because of you. Our teacher is not geart at English and so we don't really understand his explanation but you helped me out thank you
wow superb Ian its very helpful to me I got an understand on atom
really good
+Ian Stuart you are always welcome , its really effective
I like you 💜💜💜 like
I like you 💜💜💜 like
Omg you are so amazing! Man this helped me thoroughly! You are the bomb!
Thanks!!!
thank you great video
Thank you! I'm a homeschool mom, and your videos are very easy to follow. Thank you
Brilliant
Hang on, won't the extra electron in the lithium give itself away?
how can we demonstrate this?!?
Tanks,
The easy explanation in this video solved many of my doubts. Thank you.
Very clear and easy!
great video
Thank you so much, it helped me :)
Good stuff, very good presentation
thx this will help me in my exam
why hydrogen atom don't have neutron
Legend. Hands down
4.13
Then the neutron job here in the nucleus is to cement the protons to each others to keep them gathered together as one mass.
Amazing video Ian Stuart
This helped a lot.
Thank you soooooooo much 😊
great video Ian
good sir
superb
Great video, but perhaps it would have been a good idea to explain what the names of these "shells" are. It would have made things a bit more complicated, but at least a quick mention would have helped.
This was great!!!
Awesome vid it helped me understand the atom
Just saying my science teacher can't teach so this really helped
Rambabu kumar
Thank you.
I agree because the other hand is the most important things 💕💕💕💕
We have a problem... Houston 😝
I'm not sure what's nagging me in the back of my mind... I think what's bothering me is that- I mean- ok... so, Orbitals are regions around the nucleus at which an electron is likely to be found. but then, are the orbitals the shells/energy levels? are they one and the same thing?
I do know that different electrons have different energies, and that that decides how far away they are from the nucleus; this is how I understand why "energy levels" come into all of this.
I guess I'm having trouble visualising the atom with "shells" and orbitals. like, in the 3D image of the atom at the beginning, I couldn't "see" the energy levels or shells; the electrons seemed to go everywhere, like from the seemingly 3rd shell through to the first. I honestly don't know why I'm confused by this. *sigh*
Any help would be greatly appreciated! :)
The narrator has a good voice. Nothing worse than a narrator who sounds like Mickey Mouse, coughs, uses "You Know" too much, gurgles now and then or a voice tone that makes your ears hurt and sets your mind thinking about swearing or killing ...just saying
man i can't blev i watch thes shezz and i lack fnaf and I'm 9
thanks houston ;)
What happened to the neutrons?
They were left out for simplification
I have one doubt how a proton is taken out from the atom
Its cant be taken out
very good video
Hey I have an interesting question. As we all know positive charges repel positive charges and attract negative charges and vice verse. But what would happen if say in an alternate universe, positively charged particles attract positively charged particles and repelled negative particles? Now this might be impossible but it is a theoretical idea. I suspect such a universe would either continue to fuse atoms and crush back into a singularity or it would be more like a classical explosion or rather implosion and said universe wouldn't get very far before its life time ended.
Nice
that hotel mentioned is really messed up
Thnx 😍😘
good
Wish he went over the information a tad bit faster
nobody's perceiving who created this???
I don't understand your question.
dot.....
liack
