The vast majority of mass in an element is located in the nucleus, comprised of protons and neutrons. Electrons are considered to have almost no mass, although that they exist at all would imply that they must in fact have some mass.
The mass of a neutron is approx 1837 times that of an electron. The mass of a proton is similar to that of a neutron. In the simplest atom, hydrogen, the mass of the nucleus is 1,837 times that of an electron. In the largest known atom, that of ununoctium, containing 281 baryons (neutrons or protons) the mass of the nucleus is approx 516,200 times that of an electron. So take your pick: 1,837 to 516,200.
an electron is about 1/1836 amu.
Dunno, but the ratio of the mass of a proton to the mass of what prople think of as being an electron is approx 1980. I'd check that if I were you though. Probably OK to +- 5%.
1/1836 the mass of a proton
it is usually the mass without the x10^-31
The proton mass is about 2,000 times greater than the electron mass.
The proton mass is about 2,000 times greater than the electron mass.
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
The mass of an atomic nucleon is approximately 1 atomic mass unit (u) or 1.66 x 10^-27 kg. This value is commonly used as a reference unit for expressing the masses of atomic particles such as protons and neutrons.

A nucleon has more mass when it is not bound to the nucleus of an atom. When the nucleon is bound to other nucleons the binding energy that keeps them together comes from the mass of the nucleon. Therefore the mass of a single nucleon will be smaller in an atom than on it's own.
Mass ratio proton (neutron)/electron: 1 836
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.
The mass per nucleon in uranium is higher than the mass per nucleon in the fission fragments of uranium. During fission, the uranium nucleus splits into two or more smaller nuclei with a higher binding energy per nucleon, resulting in a release of energy. This difference in mass per nucleon contributes to the energy release in nuclear fission reactions.
mass of electron = 1/1836 mass of proton (or neutron)
As mass of elactron is very small as compare to proton and neutron So there will be no effect on mass if electron is removed
