Expert Solution

Step 1

In an atom three fundamental particles are present. Positively charged particle proton and neutral particle neutron present in the nucleus and the negatively charged particle electrons circulate around the nucleus. The mass of protons and neutrons is considerably higher than the mass of an electron.
