    What is Isotope - Nuclide - Definition

    Some of a given element are more abundant than others. For example 99,27% of naturally occuring uranium atoms are the 238 U, 0,72% are the 235 U and 0,0055% are the 234 U. Because all the of a given element exhibit the same chemical properties, their is very difficult by chemical means.

    Isotope separation - wikidoc

    The separation of isotopes was first suggested by Aston and Lindemann in 1919 but attempts to use the technology during the Manhattan project were unproductive and not until 1936 were the first successful experiments reported by Beams and Haynes on isotopes of chlorine. In modern times it is the main method used throughout the world to enrich uranium and as a result remains a fairly secretive …
