Answer:
-ide
Explanation:
Ionic compounds are made up of two parts: a cation and an anion. The cation is positively charged (less electrons) and the anion is negatively charged (more electrons). When naming these compounds, if the anions are nonmetals, they have their endings dropped in order to add the new ending: -ide.
Examples,
CaCl₂ ----> calcium chloride
BaF₂ -----> barium fluoride
MgO -----> magnesium oxide
