Obviously you haven't taken physics 1-3 at the university level.
This is the Pauli exclusion principle- no two identical fermions may occupy the same quantum state simultaneously.
For electrons in a single atom, it states that no two electrons can have the same four quantum numbers, that is, if n, l, and ml are the same, ms must be different such that the electrons have opposite spins.
I don't have any idea what in the hell you're talking about, you dont either.
