Explanation:

The atomic number of an element is defined as the number of protons in the nucleus of an atom of that element. The mass number is the sum of protons and neutrons. An isotope is a variant of an element with the same number of protons but different numbers of neutrons. Balanced charge refers to an atom having equal numbers of protons and electrons (neutral charge), which is not directly the same as the number of protons alone.

Answer:

C. atomic number.
