In this paper, it is hypothesized that within a free neutron there is a virtual “dormant” force carrier Z⁰ boson with the same net charge and can get “activated” by the down quark decay and transforms itself into a virtual “dormant” force carrier W⁺ boson within the newly formed proton with the same net charge and discharges the remainder, which is not a boson and has a negative charge, into an electron and an electron-antineutrino, and as the result both the charge and energy are conserved. It is demonstrated that the masses of the Z⁰ and W⁺ bosons are directly proportional to the total mass of the valence quarks in neutron and proton, respectively. Two expressions for the sum and the differences of Z⁰ and W⁺ bosons were obtained, and then the mass-energies of W and Z bosons are calculated. The calculated masses of W and Z bosons are 80.3700 GeV and 91.1842 GeV, which are in very close agreement to the reported values by the experimental results.
