Question

Quizplus · Accepted Answer

Sodium is a Group 1 element, also known as the alkali metals, and its most stable oxidation state is +1 because it has one valence electron that it tends to lose to form a stable cation with a noble gas electron configuration. Therefore, choice A is the best answer.
