A ground-state atom of vanadium has ___ unpaired electrons and is _____.
A) 0, diamagnetic
B) 2, diamagnetic
C) 3, paramagnetic
D) 5, paramagnetic
E) 4, diamagnetic

Question

Quizplus · Accepted Answer

Vanadium has 5 electrons in its 3d subshell and 2 electrons in its 4s subshell in the ground state. According to Hund's rule, the 3d electrons will occupy the five available orbitals singly before pairing up, resulting in 3 unpaired electrons, making it paramagnetic.
