Which of the following species has the ground-state electron configuration [Ar]3d⁴? A)V B)Ti⁺ C)V⁺ D)Fe²⁺

Question

Quizplus · Accepted Answer

The electron configuration given has the same number of electrons as the electron configuration of vanadium (V), which is [Ar] 3d3 4s2. However, one electron is excited from the 3d orbital to the 4p orbital, resulting in the configuration [Ar] 3d3 4s2 4p1, which matches the given configuration. Therefore, the species is likely to be vanadium with one excited electron.
