Describe how to determine the names of binary ionic compounds
Rule 1:The cation is the first name written and the second thing written is the an ion Rule 2: The name of the cation is the same as the (neutral) element Rule 3:The anion is named by adding the suffix -ide to the root of the element p. 266
