... The atomic mass of an element is the sum of all the masses of the sub-atomic particles which comprise the atom. The mass in grams of these particles (protons, neutrons, electrons, et al) are exceptionally small. The mass of the proton is 1.67 X 10-23 grams. The neutron is slightly larger and the ele ...
