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 ...

www.sas.upenn.eduAn ionic bond is an electrical attraction between two oppositely charged atoms. Normally, atoms are neutral and have no charge. However, in order to gain stability they will sacrifice their neutrality by either losing one or more of its outermost electrons thus becoming a positive ion (cation) or they will gain one or more
