Element .0. Nomenclature Rules : Individual Element Name the element exactly as it is written on the Periodic Table Compound biatomics There are seven elements that never exist by themselves, but always in pairs. Binary Two different elements bonded together. *.H2F2BraI2E Polyatomic A group of atoms that act as a unit. Consist of two or more different non-metals joined by a covalent bond. A/ways write the chemical formula in lowest terms Write the cation (metal) first, using the name from the Periodic Table. If it is a multivalent cation (highlighted) make sure to include roman numerals to identify how the cation is bonding. Or use the latin name with an ous” (lower) or “ic” (higher) ending. Write theanion (non- metal) second, dropping the usual ending and replace it with “ide”. Ionic A metal and a non metal bonded together to form a crystal lattice structure. Always write the chemical formula in lowest terms Covalent Two non-metals bonded together to form a molecule. bO NOT reduce chemical formula to lowest terms Write the name of the cation (metal) first using the name from the Periodic Table. If it is a multivalent cation (highlighted) make sure to include roman numerals to identify how the cation is bonding. . Or use the latin name with an “ous” (lower) or “ic” (higher) ending. Write the name of the polyatomic ion with the”ate” Attach a prefix that indicates the number of atoms in the chemical formula in from of the name of each element. The name of the second element ends in “ide”.
