Naming Binary Ionic Compounds

Front

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding, typically formed between metals and nonmetals.

Front

Which elements typically form cations?

Back

Metals typically form cations by losing electrons.

Front

Which elements typically form anions?

Back

Nonmetals typically form anions by gaining electrons.
