Quizplus · Accepted Answer

The electron configuration of a neutral atom that readily forms a singly charged positive ion typically has one less electron than its corresponding noble gas configuration. Among the options given, configuration 3 (7e- in the outermost shell) fits this description and represents chlorine (Cl) which will readily form a singly charged positive ion (Cl+).
