The electron has extremely small mass -- it's almost 2000 times less massive than the proton -- at approximately 9.10956 x 10 -31 kilogram (kg) or 9.10956 x 10 -28 gram (g). Every known electron at rest has the same mass as every other known electron at rest.

Electron volt - Wikipedia, the free encyclopedia
In physics, the electron volt (symbol eV ; also written electronvolt according to the NIST, IUPAC, and BIPM) is a unit of energy. By definition, it is equal to the amount of kinetic energy gaine...

For the present, we will simply consider them as VERY small "particles": the electron is negative (by convention ) and the proton is positive. The mass of the electron is 9.109 * 10 - 31 kg, the mass of the proton is 1.673 * 10 - 27 kg, and the magnitude of their electrical charge is...

Now there are equal quantities of all elements on both sides of the reaction, and mass conservation is satisfied. Balancing by inspection in this way is quick and useful when you can see the solution easily.

Quantitatively : where the intensities of the various diffracted beams are recorded as a function of the incident electron beam energy to generate so-called I-V curves which, by comparison with theoretical curves, may provide accurate information on atomic positions.
