Question

Quizplus · Accepted Answer

V has 23 electrons. To determine the ground-state electron configuration, we fill the orbitals in order of increasing energy. The 3d subshell is slightly lower in energy than the 4s subshell. The electron configuration of the neutral atom of vanadium is [Ar]4s2 3d3. The 4s orbital is filled first, so the electron configuration of V+ is [Ar]4s1 3d3. The configuration of V2+ is [Ar]4s0 3d3.
