Atoms mainly contain protons, neutrons and electrons. Atomic mass is simply the mass of an atom. In other words, it is the collection of masses of all the neutrons, protons and electrons in a single atom, speci

Atomic Number vs Mass Number Atoms are characterized by their atomic numbers and mass numbers. In the periodic table, atoms are arranged according to their atomic number. Mass number of an element is more related with the mass of it. However, it is not giving the exact mass of the atom. ...
