**Half-lives** (example: Gd)
¹⁴⁵Gd	< 1 day
¹⁴⁶Gd	1–10 days
¹⁴⁹Gd	10–100 days
¹⁵³Gd	100d–10 years
¹⁴⁸Gd	10–10,000 years
¹⁵⁰Gd	10k–103m years
¹⁵²Gd	> 700m years
¹⁵⁸Gd	Stable

This isotope table shows about all of the known isotopes of the chemical elements, arranged with increasing atomic numbers (proton numbers) from left to right and increasing neutron numbers from top to bottom.

Half-lives are indicated by the color of each isotope's cell (see colour chart to the right). Coloured borders indicate half lives of the most stable nuclear isomer states.

For this same table divided into more manageable pieces, see Isotope table (divided).
