How many electrons are in the most likely ion formed from an atom located in group 6A and period 3?

Question

Quizplus · Accepted Answer

Atoms in group 6A (or 16 using the IUPAC system) have 6 valence electrons and tend to gain 2 electrons to achieve a stable electron configuration, resembling the nearest noble gas. An atom in period 3 of this group is sulfur (S), which has 16 electrons in its neutral state. Gaining 2 electrons to form an ion, it would have 18 electrons.
