Yes and no. If you are talking about a sample of a single isotope of an element, the atomic mass number and the atomic mass are either very close or else the same. In introductory chemistry, it's probably fine to consider them to mean the same thing. However, there are two cases in...

The number of neutrons is represented by the neutron number ( N ). Because the mass of these nuclear particles is each approximately equal to one unified atomic mass unit (u), the sum of the protons plus neutrons is designated as the mass number ( A ). The mass of the electron is ...
