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.
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.
By sheer size, I would assume MUCH larger. But through weight, the proton is much heavier compared to an electron. On any element, the atomic number is the weight of the nuetrons and protons. The weight of electrons is so small and insignificant, it is usual not looked on at the highschool level. And has no effect on the molar mass.
Hydrogen is group 1 family, which is Alkali metals. Therefore, Hydrogen has 1 electron in its outermost shell. This means, it will perform +1 ion when they react. === ===
This is the electron.

an electron.
all elements have an atomic weight, because all of them have electrons and protons, and every electron and proton have a weight.
electron mass = 9.10938188 × 10-31 kilograms = 0.000548579867 atomic mass units
Electron and positron (anti-electron) have almost the same mass, with a negligible difference due to their opposite charge.

Yes, weight changes constantly as it moves through different parts of a gravitational field. However, its mass does not.
Listed in order of atmoic weight. Electrons have the majority of weight in the atom (proton, neutron, electron.)
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).
A neutron has no charge (neutron-neutral). It is simply there for weight.
The atomic weight of chlorine is 35,45.The atomic weight of chlorine is approximately 35.5 g/mol. An addition of electron is a negligible weight difference. Therefore, the mass is considered to remain the same at 35.5 grams per mole.
