NAMING INORGANIC COMPOUND WORKSHEET

Nomenclature Definition ListChemical 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
