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
