Isotope is a term for one of several forms an atom of a particular element can take. We define an atom's element by the number of protons in the nucleus, but the number of neutrons can vary. Each of the naturally occurring variations is called an isotope, even when the variation is the most common form of the element.Web

Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number. A property closely related to an atom's mass number is its atomic mass.Web
