CBSE - IX - Chemistry - Structure of the Atom
In K, L,M, N shells,in the N shell it can accommodate 32 electrons. So why the outermost shell can accommodate only 8 shells?
An atom's electron shells are filled according to the following theoretical constraints:
- Each s subshell holds at most 2 electrons
- Each p subshell holds at most 6 electrons
- Each d subshell holds at most 10 electrons
- Each f subshell holds at most 14 electrons
- Each g subshell holds at most 18 electron
- Orbitals are filled in the order of increasing n+l;
- Where two orbitals have the same value of n+l, they are filled in order of increasing n.
