The mass number of an isotope indicates the total number (the sum) of protons and netrons in an atom.

The number of protons is determined by the atomic number.

The number of neutrons can be found by subtracting the atomic number from the mass number.

What term best indicates the total number of neutrons and protons in a particular isotope of an element?

The atomic mass number is the sum of the protons and neutrons of an element. The protons are given by the atomic number, so the neutrons can be found by subtracting the mass number by the atomic number. Both the mass and atomic numbers can be found on the periodic table.
