Summary of Naming Rules

Summary of Naming Rules. Naming Ionic Compounds. Rule number #1: Make sure you actually have an ionic compound or not!. An Ionic Compound must have a METAL (except in the case of ammonium NH 4 +1 ) and a NON-METAL. Example: CrO consists of chromium and Oxygen. metal. non-metal.

  1. Summary of Naming Rules

  2. Naming Ionic Compounds Rule number #1: Make sure you actually have an ionic compound or not! An Ionic Compound must have a METAL (except in the case of ammonium NH4+1) and a NON-METAL Example: CrO consists of chromium and Oxygen metal non-metal Cation Anion

  3. Rule number #2: Write out the correct names for the parts of the ionic compound Example: Cr is NOT Chlorine or Carbon or Cryptonite! It is chromium! CrO chromium and oxygen

  4. Rule number #3:Put an –ide on the ending of the non-metal if it is just an monatomic anion such as Cl or Br or F. Example: Chromium Oxide CrO

  5. Rule number #4: Figure out if you need a Roman numeral in the name. CrO Cr definitely can have more than one charge: Cr+2 or Cr+3 so a roman numeral is needed Cr+2 or Cr+3

  6. Rule number #3: Figure out what the Roman numeral should be. ? ? Cr O-2 chromium oxide Oxygen ALWAYS has a charge of -2 Therefore the Cr has to be +2 the formula is: Chromium (II) Oxide
