6
AP Chemistry

• Day 12
• Naming Binary Ionic Compounds

7
Bonding elements

• All molecules want a net charge of Zero
• All molecules want 8 electrons in outer shells of
  their element (except H and He, which need 2)

1 1- 0
Na binds Cl- forming NaCl (net charge zero)
2 1- (2) 0
Pb2 binds I- forming NaI2 (net charge zero)
8
Binary Ionic (type 1) naming

• Cation always named first, anion second.
• 2. Cation takes name from element name. (Na is
  called sodium)
• Anion is named by adding an
• ide to root of element name. (Cl- is called
  chloride)
• NaCl is Sodium Chloride
