Each atomic orbital can hold 0, 1 or 2 electrons.
4. The Spin Quantum Number. Given the symbol “s”.
This describes the spin of the electron in the atomic orbital.
There are just 2 possible spins: clockwise and counterclockwise.

Hund's rule
: 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.
