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

Question

Quizplus · Accepted Answer

The sulfide ion (S^2-) has an electron configuration that reflects the addition of two electrons to the neutral sulfur atom to achieve a noble gas configuration. Sulfur's atomic number is 16, so its neutral atom configuration ends in 3s^2 3p^4. Adding two electrons fills the 3p orbital, resulting in the electron configuration of argon ([Ar]), which is the noble gas configuration sulfur achieves as a sulfide ion.
