(Do you have your exam calculator?) Naming from Formula-First Step
Find the Category of the Compound
Ionic compounds. 1. Metal + nonmetal(s).
Binary ionic (eg NaCl) or compounds with polyatomic ions
(eg KNO3). Ionic Formula-to-Name:
Overview of Rules for Ionic Compounds • Strategy: identify cations and anion
• Write systematic name by simply naming the ions if cation is: defined charge, “Type I – metals” metal name
polyatomic ion = name of polyatomic ion
variable charge, “Type II – metals” metal name(&charge) if anion is:
nonmetal = stem of nonmetal name + ide
polyatomic ion = name of polyatomic ion Molecular compounds. 2. 2 or more nonmetals (eg. CHCl3)
Acids—Formula starts with H and contains nonmetals. Acids are molecular, but they behave as ionic when
dissolved in water. Both binary (eg HCl) and oxyacids (eg H2SO4) exist. • Some ionic compounds have common...
