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.
To obtain the nucleon number of an ion, you add together the number of protons and the number of neutrons in its nucleus. The nucleon number represents the total count of these particles, which collectively make up the mass of the ion. For example, if an ion has 6 protons and 6 neutrons, its nucleon number would be 12.
The nucleon number, also known as the mass number, is the total count of protons and neutrons (collectively called nucleons) in the nucleus of an atom. It is represented by the symbol ( A ) and helps identify the isotope of an element, distinguishing between different forms of the same element that have the same number of protons but different numbers of neutrons. For example, carbon-12 has a nucleon number of 12, while carbon-14 has a nucleon number of 14.
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%.
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.
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.
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
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.

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.
This is not something I really know anything about, but I do know that energy is liberated in the process, so you could expect it to be less in the fission fragments. It also depends on the nucleus. Proton and neutron masses differ somewhat, so it depends on what the ratio of protons and neutrons is as well.
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
