An isotope is a form of a chemical element whose atomic nucleuscontains a specific number of Neutron s, in addition to the number of proton s that uniquely defines the element. The nuclei of most atoms contain neutrons as well as protons.
The isotope of an element is defined by the nucleon number, which is the sum of the number of protons and the number of neutrons in the atomic nucleus. The nucleon number is customarily written as a superscript preceding the chemical symbol for the element. For example,
16O represents oxygen-16, which has 8 protons and 8 neutrons, while
12 C represents carbon-12, with 6 protons and 6 neutrons. These are the most common naturally occurring isotopes of oxygen and carbon, respectively. Some carbon-14 is found in nature. An atom of carbon-14 contains 6 protons and 8 neutrons and is denoted 14 C.
