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 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. In graphical browsers, each isotope also has a tool tip indicating its half-life.

each color represents certain range of length of half-life, and the color of border indicates the half-life of its nuclear isomer state. some nuclides has multiple nuclear isomers, and this table noted the longest one. (but most likely, they're in the same color range.) those dotted border means it has a nuclear isomer, and it's color is same as the normal counterpart.

for more information about isotopes, isomers and isotones. or some other factors about them, Table of nuclides has the information.
