Compare the charge and mass of protons and electrons.

Charge:

The electronic charge of the proton and the electron both are same. Only there is a change on sign.

Since proton has a positive charge thus its charge is +1.6 × 10^-19 C

Whereas electron has negative charge so the charge of electron is -1.6 × 10^-19 C.

Mass:

The proton is much heavier in weight whereas electrons have negligible weight.

The weight of proton is 1.67 × 10^-24 g whereas the mass of the electron is 9.31 × 10^-28 g.
