Atomic Structure and Isotopes

1. Protons

   • Found in the nucleus
   • Relative Atomic Mass = 1
   • Relative Charge = +1
   • Atomic Number = Proton Number

2. Neutrons

   • Found in the nucleus
   • Relative Atomic Mass = 1
   • Relative Charge = 0

3. Electrons

   • Found in the outer shells of the atom
   • Relative Atomic Mass = Almost Nothing
   • Relative Charge = -1
