1. Chemical formulation 3
Ion groups

2. Ion groups E.g. Sodium hydroxide = NaOH Cation =Na+ Anion= OH-
Anions made up of more than one element. They act like one atom
E.g. Sodium hydroxide = NaOH
Cation =Na+ Anion= OH-
Calcium hydroxide
Ca2+ OH-
Ca2+ OH- OH-
= Ca(OH)2

3. Ions that Contain Oxygen
There are many atoms that form several different ions with oxygen. Memorize these ions!
OH = hydroxide
  PO43-    = phosphate
  SO42-    = sulfate
  NO3-    = nitrate
  ClO3-    = chlorate
  CO32-   = carbonate
CrO42-   = chromate
