REVIEW

• From the periodic table what is the ion charge going to be for Ba?

• Remember this is based on valence electrons • Small number VE - atom likely to give electrons away and

become cation (+)

• Large number VE – atom likely to take electrons and become anion (-)

WRITE THE FORMULA FOR THE FOLLOWING COMPOUNDS

• Barium Nitrate

• Barium Sulfate

• Barium Carbonate

• Barium Chlorate

• Barium Phosphate

• Ba(NO3)2

• BaSO4

• BaCO3

• Ba(ClO3)2

• Ba3(PO4)2

• Ba(NO3)2

• BaSO4

• BaCO3

• Ba(ClO3)2

• Ba3(PO4)2
