The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus. An atom that loses one or more valence electrons to become a positively charged ion is known as a cation, while an atom that gains electrons and becomes negatively charged is known as an anion. Atomic number denotes the number of protons or electrons in an atom.    Electron Configuration agreement. So, this case we have 16 protons and we have 16 neutrons, so if you add the protons plus the neutrons together, you're going to get your mass number.
