What is the ground-state electron configuration of a Cl ^ ion? A)1s²2s²2p⁶3s²3p⁴ B)1s²2s²2p⁶3s²3p⁵ C)1s²2s²2p⁶3s²3p⁶ D)1s²2s²2p⁶3s²3p² E)1s²2s²2p⁶3s²3p⁸

Question

Quizplus · Accepted Answer

The correct electron configuration for the given ion is 1s^2 2s^2 2p^6 3s^2 3p^6, which corresponds to a noble gas configuration with 18 electrons in total. This matches option C, which correctly lists the full electron configuration for an atom or ion with 18 electrons, following the order of filling of atomic orbitals (1s, 2s, 2p, 3s, 3p).
