n: 1, 2, 3, 4, etc.
2
Q
Sublevel
A
cursive L: 0
3
Q
Orbitals
A
m(subscript cursive L): +L…..-L
4
Q
Electron Spin
A
m(subscript s): +1/2, -1/2
5
Q
Excited State
A
When electron is above its ground state
6
Q
Ground State
A
When electron is at its original state
7
Q
Hund’s Rule
A
every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
8
Q
Aufbau Princible
A
electrons orbiting one or more atoms fill the lowest available energy levels before filling higher levels
