Honors WKSHT 4-4
Naming Type 2 Ionic Compounds - Notes
Ionic Bond ~ Transition Metal + Nonmetal
Transition metals can have more than one charge, so the name and formula has to reflect the charge of the metal
in the compound name.
Naming
 Write the name of the metal,

Determine the charge on the metal cation from the anion in the formula and the ratio of anion to cation,

Put the charge on the metal in roman numerals inside parentheses after the metal name,

Name the nonmetal anion with “ide” ending.

Naming Type 2 Ionic Compounds - Notes
Ionic Bond ~ Transition Metal + Nonmetal
Transition metals can have more than one charge, so the name and formula has to reflect the charge of the metal
in the compound name.
Formulas
 Write symbol for the metal with charge (from roman numeral!) and nonmetal with charge from periodic
table.
 Balance charges between metal and non-metal so the compound is neutral. (or use cris-cross)
 Sum of charges for an ionic compound must = zero!
