Question

Mass of an electron is about 1/2000times that of proton

Answer 1

Electrons are extremely small. Themass of an electron is only about1/2000 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 \(+1\).
