Rules for naming inorganic compounds
IONIC COMPOUNDS
Binary ? compounds with only two elements!
1. Name the cation (usually the metal ion) using the
same name as the element.
2. If the cation forms more than one ion, use a Roman
numeral following the element name to indicate the
oxidation state OR use the Latin form of the name to
indicate oxidation state.
3. Name the anion by using the first syllable of the
element followed by the suffix ?ide ? where more than
one syllable of the element name is needed is obvious.
4. Remember, the cation is always named first.
EXAMPLES:
MgCl is Magnesium Chloride
MgF is Magnesium Fluoride
FeCl2 is Iron II Chloride
Other Ionic compounds ? those with multiple elements
1.
2.
Name the cation as in binary compounds
Name the polyatomic ion
EXAMPLES:
MgSO4 is Magnesium Sulfate
Zn(NO2)2 is Zinc II Nitrate

Negative ions are “anions”
Positively charged ions are called “cations”
A polyatomic ion is a group of covalently bonded atoms that have an electric
charge. In a binary ionic chemical reaction they act as a single atom
