Atomic Structure

• Atoms:


  Made up of sub-atomic particles - Proton, Electron, Neutron
• Sub-atomic Particles

  • Proton +1 1 Nucleus
  • Neutron 0 1 Nucleus
  • Electron -1 1/1840 Shells surrounding nucleus
• Isotopes

  • Atoms w/ different number of neutrons
  • Periodic tables use average mass
• Calculating Av. Mass:

  • Isotope type x num of it's atoms
  • do for all
  • Add the products together
  • Product / 100 = average
