1. Ionic w/Transition Metals Ionic w/ Polyatomic Covalent
Writing Formula from Name
Write out ions, criss cross number of charge to make subscripts, reduce
Prefix tells you the number of each element
Example
Aluminum oxide  Al2O3
iron(II) oxide
 FeO
iron(II) hydroxide
 Fe(OH)2
Dihydrogen monoxide  H2O
Writing Name from Formula
Name (+) ion, name (-) ion with ending ide
Name(+) ion with roman numeral indicating charge, name (-) ion with ending ide
Same as ionic, but use polyatomic ion name instead
Use prefixes before each to tell # of atoms, ending of 2nd to -ide
BaCl2  barium chloride
MnO2  manganese (IV) oxide
(NH4)Cl  ammonium chloride
N2O5  dinitrogen pentoxide

2. Acid Nomenclature
Acids are compounds that form H+ in water with formulas usually begin with ‘H’.
Hydro + element-”ic” for hydrogen and element
-ate polyatomics  -ic acid
-ite polyatomcs  -ous acid
Examples:
HCl (aq) – hydrochloric acid
HNO3 – nitric acid
H2SO4 – sulfuric acid O H N O O
