  1. Isotopes, e- config

  2. How can hydrogen have an atomic mass that is 1.00794? How is atomic mass calculated?

  3. Hydrogen Isotopes Isotope- atoms of the same element with different numbers of neutrons

  4. Answer Protium makes up 99.98% of all hydrogen atoms Atomic Mass is average mass based on abundance

  5. Electron Configuration Electrons are distributed in energy shells around the nucleus. Each shell holds a certain amount of electrons Why?

  6. Energy Shell Electrons 2/8/8/2 for the first 20 elements

  7. Practice Example: Lithium, Atomic #3 Sulfur, #16 Carbon, # 6 Calcium, # 20

  8. Now-Just the Outer Shell! Lewis Dot Structure: Carbon Lithium: Sulfur: Calcium:
