Unit: Chemical Names and Formulas Day 3 - Notes Unit: Chemical Names and Formulas Formula to Name for Ionic Compounds
After today you will be able to… Identify polyatomic and monatomic ions and name them properly Write the chemical formulas and names for ionic compounds
Chemical Formula to Name Recall the format for chemical formulas… (name of cation – metal) (name of anion – nonmetal) Examples: KBr CaI2 Na(SO4) Potassium Bromide Calcium Iodide Sodium Sulfate
For elements with more than one possible charge (transition metals)… Use the charge on the anion to determine the charge on the cation! Example: Fe2(CrO4)3 +6/2=+3 -2(3)=-6 Iron (III) Chromate
Example: Sn(CO3)2 +4 -2(2)=-4 Tin (IV) Carbonate
Example: Cu3P +3/3=+1 -3 Copper (I) Phosphide
Example: Co2(CrO4)3 +6/2=+3 -2(3)=-6 Cobalt (III) Chromate
