Atomic Charge Gif Nanotechnology Study Guide Absolute Beginners Why are electrons disregarded when determining the mass of an atom. . The protons consist of point-like particles known as up and down quarks. In other words the electrons mass is negligible which means so small that it can be ignored. 1 and a smaller mass than a proton D. The amount of mass that an atom gets from its electrons is so tiny that for most purposes we can just ignore it. The neutron helps keep the nucleus together. They disregard the mass of the electrons because they it is so very. The first evidence of the neutrino was that the conservation of mass energy and momentum were not present in nuclear decay equations. Nuclei consist of neutrons and protons. Again physicists like simple things so one often expresses the eff...
