Question

Quizplus · Accepted Answer

Zn^2+ (choice C) does not have a noble gas configuration in its ground state because after losing 2 electrons, it achieves a [Ar]3d^10 configuration, which is not a noble gas configuration. Noble gases have filled s and p orbitals in their outermost shell, but Zn^2+ has a filled d subshell in addition to filled s and p orbitals in the shell before it.
