Naming Ionic Compounds

Question 1

Formula > Name

If it is a metal (or ammonium) that only forms one ion*

Answer 1

Name the metal than name the anion

CaCl2- calcium chloride

Question 2

Formula > Name

If the metal forms more than one ion

Answer 2

The figuore out rhe charge on the metal. Name the metal and the anion and put the charge on the metal in paranthases after the metal

Fe(ClO4)2- iron (II) perchlorate
Cr2O3- chromium (III) oxide

Question 3

Name > Formula

Write the formula for the ions involved

Answer 3

Then figure out how those ions combine to form a neutral compound

Sodium oxide- Na+ and O2- = Na2O
Iron(III) sulfate- Fe3+ and SO4^-2 Fe2(SO4)3
