The electronic configuration of an atom is determined by the Aufbau principle, which states that electrons fill lower energy orbitals first, followed by higher energy orbitals. Hund's rule states that when electrons occupy orbitals of equal energy, they first fill the orbitals singly with parallel spins before pairing up. Pauli exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers. Therefore, all three principles, the Aufbau principle, Hund's rule, and Pauli exclusion principle must be used to determine the correct electronic configuration for carbon in its ground state.
