  1. Uranium Calculate ATOMIC MASS (.007)(235) + (.993)(238) = 237.679

  2. Boron Calculate ATOMIC MASS (.199)(10) + (.801)(11) = 10.801

  3. Oxidation Number Ionic Charge = Oxidation Number

  4. Na and Cl

  5. Ca and Cl

  6. Al and O

  7. Counting Subatomic Particles • Bi • Number of protons = 83 • Number of electrons = 83 • Number of neutrons = 126 • Atomic number = 83 • Mass # = 209 • As-3 • Number of protons = 33 • Number of electrons = 36 • Number of neutrons = 42 • Atomic number = 33 • Mass # = 75 Atomic Mass = Mass #

  8. Counting Subatomic Particles • Os+4 • Number of protons = 76 • Number of electrons = 72 • Number of neutrons = 114 • Atomic number = 76 • Mass # = 190 • Te+6 • Number of protons = 52 • Number of electrons = 46 • Number of neutrons = 76 • Atomic number = 52 • Mass # = 128 Atomic Mass = Mass #
