Which of the following represents the change in electronic configuration that is associated with the first ionization energy of magnesium? A)[Ne]3s¹3p¹ → [Ne]3s¹ + e^- B)[Ne]3s² → [Ne]3s¹3p¹ C)[Ne]3s² → [Ne]3s¹ + e^- D)[Ne]3s² + e^- → [Ne]3s²3p¹

Question

Quizplus · Accepted Answer

The first ionization energy of magnesium involves the removal of one electron from the outermost 3s orbital. The electronic configuration of magnesium before ionization is [Ne] 3s2, and after ionization, it becomes [Ne] 3s1. Choice C depicts this change in electronic configuration, where one electron is removed from the 3s orbital, resulting in the formation of a stable noble gas configuration of neon ([Ne] 3s1).
