Element M has the valence electron configuration 3d⁶ 4s².What is the valence electron configuration of The M³⁺ ion? A)3d⁵ B)3d³ 4s² C)3d⁴ 4s¹ D)3d⁹ 4s²

Question

Quizplus · Accepted Answer

To determine the valence electron configuration of the M³⁺ ion, we simply remove one electron from the valence shell of the neutral M atom. The valence electron configuration of the neutral M atom is: 3d⁶ 4s² Removing one electron from the 3d orbital gives us: 3d⁵ Thus, the valence electron configuration of the M³⁺ ion is: 3d⁵, which is choice A.

Element M Has the Valence Electron Configuration 3d6 4s2

Element M Has the Valence Electron Configuration 3d⁶ 4s²
