Same!

Thanks Ajun

I love it!

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!

Thanks!!!

+GREENKAV yeah i cant spell help

I like you

It make sense now, thanks for the great insight! I am on this right now :)

+Ian Stuart you are always welcome , its really effective

I like you 💜💜💜 like

+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.

Just saying my science teacher can't teach so this really helped

Tanks,

They were left out for simplification

Its cant be taken out

I don't understand your question.
