  • What is Radioactivity?
    • Ionisation- addition or removal of atoms
    • Atomic number
      • Number of protons
        • Proton- nucleus- positive charge- mass of one
    • Atomic mass
      • Protons and neutrons in the nucleus
        • Neutron- nucleus- neutral- mass of one
    • Electron- shell- negative charge- no mass
    • Electrostatic  force tries to push the nucleus apart
      • More protons will increase electrostatic force
        • Greater than the nuclear force
          • Nucleus decays
      • Large diameter weakens strong force effect
        • Over a short distance
      • Small nucleus balances this
