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

Question

Quizplus · Accepted Answer

The correct electronic configuration for carbon in its ground state can be determined by applying all three principles: Aufbau Principle, Hund's Rule, and Pauli Exclusion Principle. The Aufbau principle states that electrons will fill the lowest energy orbitals available before filling higher energy orbitals. Hund's Rule states that electrons will occupy individual orbitals within a subshell first, and then pair up once all orbitals within a subshell are half-filled. Finally, the Pauli Exclusion Principle states that no two electrons within an atom can have the same set of four quantum numbers. By applying all three principles, we can determine that the ground state electronic configuration for carbon is 1s² 2s² 2p².
