  1. Decay Mode
    refers to type of radiation radioisotope releases as it decays
  2. radioisotope
    any radioactive isotope of an element
  3. Alpha Decay
    • when radioactive nucleus spontaneously breaks down to emit alpha particle
    • Mass decrease 4
    • Protons decrease 2
    • Neutrons decrease 2
  4. Beta Decay
    • When radioactive nucleus spontaneously breaks down to emit beta particle
    • Mass is same
    • protons increase 1
    • neutrons decrease 1
  5. Positron Emission
    • When atom emits positron as it decays
    • mass is same
    • protons decrease
    • neutrons increase 1
