Writing & Naming Formulas of Ionic & Covalent Compounds


Summing up: Ionic Ionic bonding occurs between a metal and a nonmetal. Metals lose all their valence e- and become cations. Nonmetals gain enough e- to fill their valence level and become anions. Always crisscross valences and reduce to determine the formulas of ionic compounds Do not use prefixes in the names. Ions form a crystalline lattice ...

Cations and Anions


Binary Ionic Compounds • Binary means two, and in the case of binary ionic compounds, the word binary means two elements, a metallic element and a nonmetallic element. • If a formula has a symbol for a metal and a symbol for a nonmetal, it’s a binary ionic compound composed of a monatomic cation and a monatomic anion.
