1 Cations formed from metal atoms have the same name as the metal
2 If a metal can from cations with different charges, the positive charge is indicated by a roman numeral in parentheses following the name of the metal
3 cations formed from nonmetal atoms have names that end in "-ium"
1. The names of monatomic anions are formed by replacing the ending of the name of the element with "-ide"
2.Polyatomic anions containing oxygen have names ending in either "-ate" or "-ite"
-the "ate" is used for the most common oxyanon of an element and "ite" is used for an oxyanion that has the same charge but one fewer O atom.
3. Anions derived by adding H^+ to an oxyanion are named by adding the prefix "hydrogen" or "dihydrogen"
1. Names of Ionic compounds consist of the cation name followed by the anion name
