mrnood · Answer

Have a look at an idealised model of the atom

Look at the particles which are in the nucleus - how many are there?

Look at the particles which are in the electrons - how many are there?

What is the relative mass of an electron compared with a proton or neutron?

Look these up and you will have your answer (you will also have a better understanding of the 'structure' of an atom.
