The mass of an electron is about 1/2000 times that of proton

1.	The mass of an electron is about 1/2000 times that of proton
Answer» ong>ANSWER: Electrons are extremely small. The MASS of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an ELECTRIC charge of −1, which is equal but OPPOSITE to the charge of a proton, which is +1.
