Chemistry:Ionic Nomenclature
General Pattern for Ionic compounds
Binary Compounds - Write the name of the first element then write the beginning of the second element plus –ide
Polyatomic compounds – Write the name of the first element plus the name of the polyatomic ion.
Transition metal compounds – Write the name of the first element with the oxidation number (charge) in parenthesis then write the beginning of the second element plus –ide.
TipsAnions (nonmetal ions) are the element
names with –ide at the end. ex. Chloride, oxide, and fluoride
Polyatomic ions never change their names.
Metals not in column 1 or 2 must have roman numerals to show their charge.
