1. Naming with Transition

2. Transition Elements
Called transition elements because they can make more than one ion.
They are all metals so all are (+) ions
Need some way to show which ion is involved in the compound

3. Writing Formulas
The roman numeral in the name gives the charge of the ion
Rules for naming:
Write the symbol for the cation.
Write the symbol for the anion.
Flip the charges (w/out the + or-)
Reduce if possible.
Copper II chloride
Manganese III phosphide

4. Naming Compounds Rules: Name the cation.
Name the anion. Changing the ending to –ide.
Find the charge of the cation and record as a roman numeral after the name of the cation.
CuF2
Cr2O5

5. Polyatomic Ions
Group of atoms covalently bonded together that act as a single ion.
When naming do not change the ending to –ide.
Can be used with main group elements or transition elements.

6. Examples K3PO4 Mn(NO3)2 CaCO3 Zinc II phosphate Vandaium V sulfate
Strontium phosphate
