Question

12 multiple - choice question which of the rules discussed in this lesson relates to the spin of the electrons in an orbital paul exclusion principle aufbau hunds rule rewatch

Explanation:

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers, which relates to the spin of electrons in an orbital (electrons in the same orbital must have opposite spins). The Aufbau principle deals with the order of filling orbitals with electrons, and Hund's rule is about maximizing the number of unpaired electrons with parallel spins in degenerate orbitals.

Answer:

Pauli Exclusion principle
