Question

what charge do group 16 elements form? 1 point +1 +2 +3 ±4 -3 -2 -1 0 what charge do halogens elements form? 1 point +1 +2 +3 ±4

Explanation:

Group 16 elements (such as oxygen) have 6 valence electrons. They tend to gain 2 electrons to achieve a stable electron configuration (like noble gases). Gaining 2 electrons gives them a charge of - 2. Halogens (group 17 elements like chlorine) have 7 valence electrons. They gain 1 electron to achieve a stable electron configuration, resulting in a charge of - 1. But since the first question is about group 16:

Answer:

-2
