Neutrons is the heaviest particle, because it contain both electron and proton . We know mass of the proton is (1.672623 X 10-27 kg) 1840 times heavier than that of electron mass (9.109390 X 10-31 kg). On comparing proton and electron we get a new idea that neutron (the neutral particle) have both electron and proton so mass of neutron is 1.674929 X 10-27 kg .
