hierarchical_section_title: Table of nuclides (segmented, wide)
context_page_description: These isotope tables show all of the known isotopes of the chemical elements, arranged with increasing atomic number from left to right and increasing neutron number from top to bottom.
  Half lives are indicated by the color of each isotope's cell. Colored borders indicate half lives of the most stable nuclear isomer states.
  The data for these tables came from Brookhaven National Laboratory which has an interactive Table of Nuclides with data on ~3000 nuclides.
