Here are 5 examples of isotopes, as referenced:
Isotopes are variants of a chemical element which differ in neutron number, and consequently in nucleon number. All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.
| Isotope | Element |
|---|---|
| Carbon-14 | Carbon |
| Tritium (Hydrogen-3) | Hydrogen |
| Chlorine-36 | Chlorine |
| Uranium-235 | Uranium |
| Uranium-238 | Uranium |
Some isotopes, like Uranium-235 and Uranium-238, have extremely long half-lives, on the order of hundreds of millions of years, and are often referred to as stable nuclides or stable isotopes.
