Naming ionic compounds

Write the name of cation first. Write name of anion last, followed by "ide".

The Criss-Cross Rule

a way to write the formula for an ionic compound in the lowest whole number ration of cations to anions

When writing the formula for any ionic compound, the charge of the ions must

balance

Ionic Compounds

compounds composed of cations (metals) and anions (nonmetals)

When writing formulas for ionic compounds write

the cation first followed by the anion
