What charge do elements in the same family as O usually have when they become ions?

Elements in the same family as oxygen, which is group 16 of the Periodic Table, typically have a charge of -2 when they become ions. This is due to their tendency to gain two electrons to achieve a stable electronic configuration, similar to that of the nearest noble gas. For example, oxygen forms the oxide ion (O²⁻), while sulfur can form the sulfide ion (S²⁻). Other elements in this group follow the same pattern, generally forming anions with a -2 charge.
