Question 1

what is the Aufbau Principle?

Answer 1

electrons are added to the lowest energy l orbitals available

Question 2

what is the Pauli exclusion principle?

Answer 2

No two electrons in an atom ca have the same set of four quantum numbers (n,l,ml, and ms)

Question 3

what is the Hund’s rule?

Answer 3

for degenerate orbitals, the lowest energy state is obtained when the number of electrons with the same spin is maximized. so for a degenerate
