Warm UpWrite the formula (remember you need to look at

charge!)If you have no idea how to do it, just write the

charges for each:Calcium and Fluorine

CaF2

Sodium and Oxygen

Na2OMagnesium and Sulfur

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.
