Peter Bitley House was created in 1837.
The mass of an electron is approximately 1⁄1836 of a proton. Thus as hydrogen is made of one proton and one electron, hydrogen is 1837 times heavier than an electron.
Mass of electron is about 1837 times less than the mass of proton
The electron has only a small fraction of the mass of the neutron. The neutron is about 1837 times as massive as the electron. The proton is just a tiny bit less massive as the neutron, so the proton and neutron are said to have about the same amount of mass.

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.
An alpha particle is a helium nucleus, consisting of 2 protons and 2 neutrons. Beta particles are fast moving electrons that are emitted from a nucleus when a neutron decays into a proton and an electron. Since 1 electron has 1/1837 the mass of a proton, the alpha particle is roughly 7348 times the mass of the electron.
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.

The three particles that make up an atom are protons, neutrons and electrons. Protons and neutrons both have a mass of 1 unit, whereas the mass of an electron is 1/1837 of that of a proton or a neutron. Therefore, the electron has the least mass as its mass is considered negligible.
About 1837.This is why you can safely ignore the mass of electrons for any known element in rough calculations; the total mass of the electrons will be well under 0.1 amu.
In the atom: Neutron: Mass: 1,00866491600(43) amu. Electron: Mass: 5,4857990946(22)×10−4 amu. Proton: Mass: 1,007276466812(90) amu.
Answer*Relative Mass*Protons have a relative mass of 1 compared to neutrons.Neutrons have a relative mass of 1 compared to protons.Electron =5.45 x 10-4
