Periodic table for looking up element numbers (atomic number )The isotope tables given below 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 (see color chart in each section). 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 with data on ~3000 nuclides.
