The atomic number (also known as the proton number) is the number of protons found in the nucleus of an atom. It is traditionally represented by the symbol Z. The atomic number uniquely identifies a chemical element.

In scientific writing, the mass number is usually located to the upper left of an atom’s symbol. When given together with the atomic number, or the number of protons, the mass number tells an atom’s element and isotope.

What is the definition of mass number?
