  1. What type of atoms form covalent bonds?
    • Nonmetals
    • Electrons are shared by both atoms
  2. Chemical Formula for Sulfur dioxide
    SO2
  3. Chemical Formula for Silicon Tetrachloride
    SiCl3
  4. Chemical Formula for Dinitrogen oxide
    N2O
  5. Chemical Formula for Tetraphosphorus hexoxide
    P3O6
  6. Ionic Compounds
    • Formed with negative and positive ions
    • (no sharing of electrons)
    • Held together by Ionic bonds
    • Found in Ionic Lattice
  7. Bond Types based on electronagtivity
    • Greater than 1.7=ionic bond
    • 1.7-0.4=polar covalent
    • Less than 0.4=Non Polar covalent
  8. Naming Ionic Compounds
    • Metal ion (cation) first-keeps elemental name
    • Nonmetal (anion) second-replaces ending with ide
  9. Name the following ionic compounds:
    MgCl2
    Al2O3
    NaBr
    • Magnesium Chloride
    • Aluminum Oxide
    • Sodium Bromide
  10. Transition Metals
    Need to indicate charge of an ion because they have more than one charge state.
  11. What do you do if more than one polyatomic ion is needed?
    surround it with ()
