How do electron shells and subshells work?

[bayan]

hi guys.

Today we were doing the shells and subshells in school and I didn't really get the damn thing. I tried to search it on google but had no luck by my side :(

Could someone explain how it is or provide a link please.

Thanx

Try http://www.colorado.edu/physics/2000/index.pl . It helped me when I was in year 11.

I found agood explanation of this in 'The Periodic Kingdom' by Peter Atkins There is a link to similar diagrams here :

There are also various programs that you can download to give 3d visualisations of electron shells to run on your computer since personally I find it impossible to visualise anything that complex without really good animation .

One can also google on "electron configuration"
