1
Q
what is the Aufbau Principle?
A
electrons are added to the lowest energy l orbitals available
2
Q
what is the Pauli exclusion principle?
A
No two electrons in an atom ca have the same set of four quantum numbers (n,l,ml, and ms)
3
Q
what is the Hund’s rule?
A
for degenerate orbitals, the lowest energy state is obtained when the number of electrons with the same spin is maximized. so for a degenerate
