The Atomic Mass of an element depends on the weight of the protons, neutrons, and electrons (almost negligible) in one mole (6.022 x 10^23 atoms) of the element.
The contents of the Nucleus account for the Atom's Atomic Mass. The mass of the electrons is negligible in comparison and is ignored.
electrons
Proton and neutron have similar mass, but not identical.
<P>proton + neutrons give you a nucleon. the nuceon(or protons +neutron) give you the overall mass of the atom. the mass of electrons is not included, i dont even think that it has mass at all. Hope you're answered?</P>
Number of neutrons = Mass number - Number of protons = 4 - 2 = 2 neutrons
No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons. Therefore, an alpha particle has approximately 4 times the mass of a proton or neutron.No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons.

It is about the helium gas. mass number of it is 4.
Reduces the number by 2 and the mass by 4.
About 2% of an atom's mass is caused by the Higgs boson. The rest is due to the effect of the Strong Nuclear Force.

The atomic number of helium is 2. Its mass is 4.002602 u ± 0.000002 u
