Definition of Isotope
An isotope is a variant of a particular chemical element that shares the same number of protons but has a different number of neutrons within its atomic nucleus. This results in the same atomic number but a different atomic mass. For example, carbon has several isotopes, including carbon-12 (with 6 protons and 6 neutrons) and carbon-14 (with 6 protons and 8 neutrons)....
