trans-iron element

(elements with atomic number greater than that of iron)

A trans-iron element is an element with an atomic number greater than 26, that of iron. Their origin is of interest because the processes that synthesize elements (nucleosynthesis) generally work up to iron from below and because iron is highly stable, are far less likely to continue and produce heavier elements. The r-process is presumed to be a means.
