How to find isotopes 6 Isotopes and Atomic Masses” In Principles of General Chemistry (v. Isotopes and Atomic Structure Atomic Number and Mass Number. See examples, exercises, and explanations of the difference between mass number, atomic mass, and average atomic mass. Isotopes are atoms of the same element that have different number of neutrons. This time, the relative abundances are given as percentages. The symbol for a specific isotope of any element is written by placing the mass number as a superscript to the left of the element symbol (Figure \(\PageIndex{4}\)). Since zinc (Zn) has an atomic number of 30, this isotope contains 30 protons and 30 electrons. The abundance tells you how common the isotope is, as a percentage of all atoms of the element.
