Writing & Naming Formulas of Ionic & Covalent Compounds
scienceperks.weebly.comSumming 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 ...
