tise compound name
Binary (two-element) ionic compounds consist of a metal and a nonmetal. The compound’s name is composed of the name of the metal as it appears in the periodic table, followed by the name of the nonmetal element with its ending replaced by -ide. Compounds containing monatomic ions have their charge specified by adding a Roman numeral to the name of the metal; for example, iron chloride is named FeCl2. More complex ionic compounds can contain polyatomic ions, which can have different charges. These are distinguished by placing the charge in parentheses after the metal name; for example, FeCl2 is named iron(II) chloride and FeCl3 is called iron(III) chloride.
