Dear student

The charge of electron is –1.60217662 × 10-19coulombs


Electron has relative mass of 1 / 1840 u, proton has 1u and neutron also has 1u.
Electron has relative charge of -1u, proton has +1u and neutron has 0 relative charge.

Protons and neutrons have approximately the same mass, about 1.67 × 10-24grams. Scientists define this amount of mass as one atomic mass unit (amu) or one Dalton. Although similar in mass, protons are positively charged, while neutrons have no charge. Thus, the number of neutrons in an atom contributes significantly to its mass, but not to its charge.Electrons are much smaller in mass than protons, weighing only 9.11 × 10-28grams, or about 1/1800 of an atomic mass unit.

Thanks
