Question

what is the correct name for mgf₂?
a. magnesium difluoride

Mg is magnesium, a metal. F is fluorine. In naming ionic compounds, the metal name is written first followed by the non - metal name with the ending changed to - ide. Prefixes are not used for ionic compounds with main - group metals like magnesium. So, MgF₂ is named magnesium fluoride.

C. magnesium fluoride
