Isotope table (complete)

Encyclopedia : I : IS : ISO : Isotope table (complete)


isotopes of the chemical elements, arranged with increasing atomic numbers (proton numbers) from left to right and increasing neutron numbers from top to bottom.

Half-lives are indicated by the color of each isotope's cell (see color chart to the right). Colored borders indicate half lives of the most stable nuclear isomer states.

For this same table divided into more manageable pieces, see Isotope table (divided).
