Which, if any, is the ground-state electron configuration for Ni²⁺ A) [Ar]3d⁶ or 1s²2s²2p⁶3s²3p⁶3d⁶ B) [Ar]3d⁷ or 1s²2s²2p⁶3s²3p⁶3d⁷ C) [Ar]3d⁸ or 1s²2s²2p⁶3s²3p⁶3d⁸ D) [Ar]3d⁹ or 1s²2s²2p⁶3s²3p⁶3d⁹ E) None of the above

Question

Quizplus · Accepted Answer

The ground-state electron configuration for Ni is [Ar]3d⁸4s². When it loses two electrons to form Ni²⁺, the electrons are removed from the 4s orbital, resulting in [Ar]3d⁸.
