Which principle(s) or rule must be used to determine the correct electronic configuration for any atom in its ground state

Hund's rule

Pauli exclusion theory

Aufbau principle

Explanation:

Hund's rule states that, in the filling of degenerate orbitals, electrons occur singly first before pairing takes place.

Pauli exclusion theory states that no two electrons in the same atom can have the same value for all four quantum numbers.

Aufbau principle states that lower energy orbitals are first filled before the higher energy orbitals.

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
