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
The neutron number, symbol ''N'', is the number of neutrons in a nuclide.
Atomic number (proton number) plus neutron number equals mass number: . The difference between the neutron number and the atomic number is known as the neutron excess: . ...
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 interactiv
Table of Nuclideswith data on ~3000 nuclides. Recent discoveries are sourced from M. Thoennessen's "Discovery of Nuclides Project" websit
