All atoms are made of 3 Sub-atomic particles;

  • Proton has a charge 1+ and relative mass 1
  • Neutron has no charge and relative mass 1
  • Electron has a 1 charge and relative mass 1/1840


  • Atoms of the same element but different mass number
  • has the same amount of protons and electrons but different amount of neutrons which mean there would be slightly different…
