Question

Quizplus · Accepted Answer

The ground state electron configuration of Scandium (Sc) is [Ar] 3d^1 4s^2, which translates to filling the 1s, 2s, 2p, 3s, 3p orbitals completely (following the Aufbau principle), and then placing one electron in the 3d orbital and two electrons in the 4s orbital. This is accurately represented in choice D, which follows the correct order of orbital filling and matches the electron configuration for Sc.
