Ionic comes from ion as you might have guessed. An ion is a charged particle (either positive or negative), and ionic is the adjective meaning charged. An ionic bond is a chemical bond based on electrostatic attraction (the attraction of charges), and we generally associate it with the bonding of metals to non-metals.
An ionic compound in chemistry refers to any chemical compound in which ions are held together, or bound, through ionic bonds. Ionic bonds, by definition, are electrostatic attractions between two ions with an opposite charge. In other words, an ionic bond can only form between a cation and an anion. Although there is no limit to the number of ions contained in an ionic compound, in order for the compound to remain whole, the net charge needs to equal zero.
