ISOTOPES

• Isotopes

  • different numbers of neutrons, same number of protons and electrons
  • naturally occurring
  • difference in mass
• Isotones

  • same number of neutrons
• Isobars

  • same mass number but different atomic numbers
• Artificial Isotopes (radioisotopes)

  • can be product from heavier elements
  • highly unstable, in nuclear reactions
  • bombarded with neutrons
• Beryllium, Fluorine, and Sodium don't have isotopes
