Best Answer

Mass number in chemistry is the number of nucleons in the nucleus. Nucleon is the common name for proton and neutron. In case of Sodium atom the mass number is 23. If it gets changed by adding one more neutron then it is an isotope which is used in medical field as a radio isotope to study about the blood flow.
