Unformatted text preview: Nomenclature – system of naming chemicals N.3 1. Monatomic: an ion formed from a single atom A. Non –ions: diatomic in nature; made up of two atoms that are chemically bonded to each other. They are H 2 , N 2 , O 2 , F 2 , Cl 2 , Br 2 , I 2 (all halogens) B. Ions: the charged particle formed when an atom gains or loses electrons. If the atom has a positive charge it is a cation , if it has a negative charge it is a anion . Examples: Li+, K+, Cl-, Mg 2+ i. Cation: ions with a positive charge; elemental name + ion Example: Na+ - sodium ion, Al+ - aluminum ion ii. Anion: ions with a negative charge; elemental name + ide ion Example: Cl- chloride ion, O 2- oxide ion, P 3- phosphide ion N.4 Formation of a monatomic ion from an atom expressed in a chemical equation: Group 1A (1), sodium ion: Na → Na+ + e- Group 2A (2), magnesium ion: Mg → Mg 2 + + 2 e- Group 3A (3), aluminum ion: Al → Al 3 + + 3 e- Formation of nonmetals in Groups 5A, 6A & 7A form monatomic ions by gaining electrons...
