Hydrogen contains 1 proton , 1 neutron and 1 electron. so its pretty easy to compare the electrons protons and neutrons.
We use relative masses to calculate:
The atomic mass unit is (1/12)th of the mass of the carbon ( 12 .6 C ) atom .
Atomic mass unit (a.m.u), it measures nuclear masses
Protons and neutrons. These have nearly the same mass. Together they make up the nucleus which compromises nearly all the mass of the atom.
Electrons - roughly zero mass relative to the nucleus.
Neutron = 1.6749286*10-27 kg
Proton = 1.6726231*10-27 kg
Electron = 9.1093897*10-31 kg
