An ionic compound is composed of a cation (generally, a metal ion) and an anion (a nonmetal ion). The cation and the anion combine due to the Coulombic force of attraction to form an ionic lattice. The metal atom releases one or more electrons and the nonmetal receives these electrons until they fulfill their octet.
Ionic compounds are held together by opposite charges but do not have a charge. You have to balance the +’s and -‘s. Ba has a charge of +2 F has a charge of -1 You need 2 F- to balance the +2 of Ba BaF2.
a) BaF2 or barium fluoride
b) CsCl or cesium chloride
c) Li3N or lithium nitride
d) Al2O3 or aluminum oxide
