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.
