<u>Answer: </u>The term is Mass number.

<u>Explanation:</u>

Atomic number is defined as the number of protons or number of electrons present in an atom. It is represented as Z.

Z = Number of protons = Number of electrons

Mass number is defined as the sum of number of protons and neutrons in an atom. It is represented as A.

A = Number of proton + Number of neutrons

Hence, the correct answer is Mass number.
