Report Abuse. 1  Atoms are composed of three type of particles: protons, neutrons, and electron. Protons and neutrons are responsible for most of the atomic mass e.g in a 150 person 149 lbs, 15 oz are protons and neutrons while only 1 oz. is electrons. 2  Neutrons, along with protons are located in the nucleus of the atom. This is a very small portion of the atom -- an area proportionate to a nickel on the 50-yard line of a football field. Neutrons and protons make up the vast majority of the mass of the atom and are held together by the nuclear strong force.
