  • A charged atom is called an ion and has an unequal number of protons and neutrons.
  • Isotopes are atoms  of the same element with a different number of neutrons 

An unstable nucleus becomes more stable by emitting an alpha/ beta particle or gamma radiation.

Ernest Rutherford made important discoveries relating to radioactivity. He asked 2 of his workers to investigate the scattering of alpha particles by a thin metal foil. They measured the number of alpha particles
