Isotopes |
|
Different isotopes of the same element have different numbers of neutrons in the nucleus and hence have different masses, The separation of isotopes is a difficult process because the chemistry is the same. They differ only in mass. The enrichment of naturally occurring uranium which contains only a small amount of fissionable 235U in gas centrifuges is the subject of ongoing fear and political debate. |

An Applet shows the known isotopes of the light elements, their half lives, the energy released in the decay process, and the decay products. |
