Can someone explain the principal quantum number to me please? We had a lesson it today but I'm not getting it :-/
It is just the number given to the energy level of the electrons around the atom.
The first energy level is assigned a quantum number = 1
The second energy level is assigned a quantum number = 2
etc.
