NAMING INORGANIC COMPOUND WORKSHEET Nomenclature Definition List Chemical nomenclature is concerned with naming chemical compounds and writing their formulas. Gathered below are definitions of many terms used in nomenclature. oxidation state an alternate term that can be used when referring to the charge on an atom (but not a polyatomic ion.) metalloid an element which has the capacity to act as either a metal or a nonmetal, depending on the chemical circumstances nonmetal an element that tends to gain electrons, becoming negatively charged metal an element that tends to lose electrons, becoming positively charged ion an atom or group of atoms with either a positive or a negative charge cation positively charged ion anion negatively charged ion. The phrase "ANIONS: Are Negative IONS" monatomic ion a single atom ion (mono means one) Ex: Na+ or Cl¯ polyatomic ion a many atom ion (poly means many) which acts chemically as one unit. Example: NO3¯ (1 Nitrogen atom, 3 Oxygen atoms and an extra electron giving the ion a charge of 1¯). ionic compound a compound containing at least one ionic bond (contains metal(s) & non-metal(s)) covalent compound a compound containing only covalent bonds (covalent compounds are really molecules; contains only non-metal atoms) binary compound compound with only 2 kinds of elements ternary compound compound with more than 2 types of elements Docsity.com Flow Chart for Naming Simple Inorganic Compounds The flowchart is adapted from p. 131-132 of the February 1989 issue of the Journal of CRemical Education, Does the formula Are there two begin with H? atoms, both It is ants) Does the acid contain No | Yes [——— the sarne? |_-*| acid. a polyatomic ion?
