Which principle or rule must be used to determine the correct electronic configuration for carbon in its ground state?
a.Aufbau Principle
b. Hund's Rule
c. Pauli Exclusion Principle
d. (A) and (B) only
e. All three

I know for a fact that Aufbau's and Hunds rule deal with ground state configuration i just dont know if you consider Paulis rule, which says that no two electrons can have the same 4 quantum numbers, when you are conforming an electron to its ground state?

Can any help me, my answer as of know is D but im second guessing myself with E?

The Pauli Exclusion Principle is the reason why all of the electrons in any atom don't just collapse to the first orbital. If they did, they'd all have identical quantum numbers.

Does that help?
