INORGANIC NOMENCLATURE Ionic compounds can be classified as IONIC or COVALENT 1. IONIC COMPOUNDS Binary Ionic Compounds (only 2 elements form the compound) Basic Oxides = Metal + Oxygen → Name: Metal(ox#) Oxide Most of these oxides react with water to produce hydroxidesPeroxides = Metals + Oxygen → Name: Metal(ox#) Peroxide Many peroxides decompose releasing hydrogen gas. Binary Salts = Metal + Non-metal → Name: Metal(ox#) Non-Metal-IDE More complex Ionic Compounds (More than 2 elements form the compound) Most of the time one or 2 polyatomic ions are involved. Oxo- Salts = Metal + polyatomic ion →Name: Metal(ox#) Polyatomic ionAmmonium- Salts (I)= Ammonium + Non Metal →Name: Ammonium Non-Metal-IDE Ammonium- Salts (II)= Ammonium + Polyatomic Ion →Name: Ammonium Polyatomic Ion Name 2. COVALENT COMPOUNDS Binary Covalent Compounds (only 2 elements form the compound)Covalent compounds use prefixes in both namesFormat: PREFIXelement1 PREFIXelement2IDEMono (never used in the first name)DiTriTetraPentaHexaHeptaOctaNonaDecaName the non-metal furthest to the left on the periodic table by its elemental name with the prefix if different than 1Name the second non-metal by its elemental name with the prefix and the suffix “ide” at the end.The element at the end is always the most electronegative of both. General Binary Compounds = Non-metal + Non-Metal→ Name: Prefix-element1 Prefix-element2-ideThese compounds do not have oxygen or hydrogenAcidic Oxides = Non-metal + Oxygen → Name: Prefix-element1 Prefix-oxideThese oxides react with water to produce Oxo-acids
