Quizplus · Accepted Answer

Sodium (Na) has an atomic number of 11, which means it has 11 electrons. The electronic configuration of Na is 2,8,1. The outermost shell, which is the third shell, has only one electron, which means Na has one unpaired electron in its outermost shell. Thus, the best choice is D.
