19. If I gave you BrO-, BrO2-, BrO3-, and BrO4-,
HOW would you know how to name them?

• You would first recognize the number of oxygen
  present in each formula.
• Remember the less oxygen that is present the
  name will end in ite, the more oxygen that is
  present the name will end in ate.
• If there is only 1 oxygen, then hypo- goes in
  front of the name. If there are 4 oxygens, then
  per- goes in front of the name.

So BrO- hypobromite, BrO2- bromite,
BrO3- bromate and BrO4- perbromate.
