WebAn isotope is named after the element and the mass number of its atoms. For example, carbon-12 is an isotope of carbon with a mass number of 12. WebApr 6, 2024 · While all carbon atoms have six protons and most have six neutrons, some carbon atoms have seven neutrons, while others have eight. Atoms of the same element that differ in their numbers of neutrons are called isotopes. Many isotopes occur naturally. Quite often, there are one or two isotopes of an element that are the most stable and common.
