  • Protons are the positively charged particles in an atom
  • Neutrons do not carry any charges
  • Both protons and neutrons have similar masses.
  • They contribute the bulk of the mass of the atom.
  • The electrons carry negative charges and they have negligible masses.

The mass of protons and neutrons are similar.
