Opposite Spin

Why do electrons in an orbital have opposite spins?

No two electrons can have the same four quantum numbers. If the electrons had the same spin they would have the same spin magnetic quantum number.

The Pauli Exclusion Principle states that no two electrons can share the same combination of four quantum numbers. The electrons in an orbital must have opposite spins in order for their quantum numbers to differ. Since their n, l, and ml are the same, their ms (which refers to the spin of the electron) must be different, which is why they have opposite spins.

Electrons in an orbital must have opposite spins because electrons cannot have the same four quantum numbers. The opposite spin is a distinguishing factor.

Aside from not being able to have the same four quantum numbers, electrons with opposite spin in the same subshell will maximize stability.
