Electrons behave
as if they are tiny
charged spheres

...
Quantum mechanics shows that:
Within an atom there are major energy levels which we call
shells and are designated using quantum numbers
...
The shell number = the number of subshells in that shell!
e
...
Shell 1 contains one subshell (1s)
Shell 2 contains two subshells (2s and 2p)
Shell 3 contains three subshells (3s, 3p and 3d)
Subshells are made up of atomic orbitals

Orbitals are filled in order of increasing energy

A configuration which shows an electron in a higher energy
orbital at the expense of a lower energy orbital is said to be
in an excited state
