The mass number indicates the sum of the number of protons and neutrons of the isotope. The mass number, nucleon number or atomic mass indicated about the respective chemical symbols in the Periodic Table are average figures based on the different isotopes and their relative abundance. That is why there are decimals in mass numbers in the periodic table. It can be used to compare the relative atomic masses of different atoms.

What do you get if you subtract the atomic number from the mass number for a particular atom?
You get the number of neutrons in the atom. The mass number represents the total number of protons and neutrons in the nucleus, while the atomic number represents the number of protons. Subtracting the atomic number from the mass number gives you the number of neutrons because the difference accounts for the protons.
