Electron

proton mass: 9.11\times10^{-31}kg
proton charge: -1.6\times10^{-19}C

An electron orbits the nucleus of an atom in its own energy level.

Charge

An electron has a negative charge of -1.6\times10^{-19} coulombs.
This negative charge is equal in magnitude but opposite in sign to the positive charge of a proton.

Mass

Electrons have a mass of about 9.11\times10^{-31}kg.
That makes them a lot lighter than protons and neutrons.
Its relative mass is about 1/1836 of a proton.
