Table of nuclides (complete)

The isotope table below shows isotopes of the chemical elements, including all with half-life of at least one day. They are arranged with increasing atomic numbers (proton numbers) from left to right and increasing neutron numbers from top to bottom.

Cell colour denotes the half-life of each isotope; if a border is present, its colour indicates the half-life of the most stable nuclear isomer. If you’ve scrolled so the colour legend is not in view, allowing your cursor to dwell over a cell will cause a pop-up text box to indicate that isotope’s half-life. If a cell has a white or yellow border, dwelling over it will also disclose the half-life of the most stable nuclear isomer state.
