The Pauli Exclusion Principle
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
The Pauli exclusion principle states no two electrons in one atom share the same complete set of four quantum numbers.
Show
Two electrons in the same orbital, sharing n, l, and ml, must carry opposite ms values.
Watch for
This principle limits every orbital to two electrons, since only two spin values remain once n, l, and ml are fixed.
