The interesting part for answering your question is the "mass defect", which is due to the interaction energy between the nuclei. Hence, (loosely speaking) apart from the unit mass 1 u the difference between the nuclear number and the atomic mass is the mass defect.

Web- Remember that the mass number (a.k.a atomic mass)- is the number of PROTONS and NEUTRONS in the nucleus of the atoms of that element. - The periodic table gives us the atomic number of each element. For example, Hydrogen has the atomic number of 1 and Oxygen has the atomic number of 8. Just look at the whole number on the periodic table!
