9.1*10^-31 kg
An electron, with relatively negligible mass meaning the mass of an electron is so insubstantial that it isn't counted towards the total weight of the atom.
A proton is heavier than an electron. MASS(kg): Proton - 1.67 × 10-27kg Neutron - 1.67 × 10-27kg Electron - 9.11 × 10-31 kg *A neutron is about .1% heavier than a proton.
electron mass = 9.10938188 × 10-31 kilogramsproton mass = 1.67262158 × 10-27 kilogramsProton is a factor of 10^4 times the mass of an electron.
The electron configuration of beryllium is: 1s22s2. The atomic weight (not mass) of beryllium is 9,012 183(3).

all elements have an atomic weight, because all of them have electrons and protons, and every electron and proton have a weight.
If the electron were the size of a golf ball, the proton would be about the size of a basketball and the electron would be orbiting about 8000 meters away (assuming the Bohr model of the atom).
No, the electron cloud is not heavy. An electron weighs approximately 2000 times less than a proton or a neutron, so almost all the weight of an atom lies in the nucleus, not in the electron cloud.
A neutron has no charge (neutron-neutral). It is simply there for weight.

Listed in order of atmoic weight. Electrons have the majority of weight in the atom (proton, neutron, electron.)
Yes, weight changes constantly as it moves through different parts of a gravitational field. However, its mass does not.
The mass of an electron is 9.109 382 15(45) × 10-31 kilograms (Kg). On Earth the weight of an electron is the mass times gravity. That is about 8.9278 x10-30. As a note, due to Newton's Second Law, which states F=ma, that is also the force of an electron of 1 Coulomb.
