Warm Up
 Write 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
Na2O
 Magnesium and Sulfur
MgS
 Lithium and Chlorine
LiCl
 Cesium and Iodine
CsI

Ionic Nomenclature
Unit Five, Day One

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.
Tips
 Anions (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.
