Which of these choices is the electron configuration of a sulfide ion? A) [Ne] B) [Ne]3s²3p² C) [Ar] D) [Ne]3s²3p¹ E) [Ne]3s²3p⁴

Question

Quizplus · Accepted Answer

The sulfide ion (S^2-) has an electron configuration that ends with the noble gas configuration of argon ([Ar]). This is because sulfur, with an atomic number of 16, gains two electrons to fill its valence shell, similar to the electron configuration of argon, which has 18 electrons.
