It is the lowest atomic number<http://en.wikipedia.org/wiki/Atomic_number> element without any stable isotopes <http://en.wikipedia.org/wiki/Stable_isotope>; every form of it is radioactive <http://en.wikipedia.org/wiki/Radioactive>. Nearly all technetium is produced synthetically and only minute amounts are found in nature. Naturally occurring technetium occurs as a spontaneous fission product <http://en.wikipedia.org/wiki/Fission_product> in uranium ore<http://en.wikipedia.org/wiki/Uranium_ore> or by neutron capture <http://en.wikipedia.org/wiki/Neutron_capture>in molybdenum <http://en.wikipedia.org/wiki/Molybdenum> ores. The chemical properties of this silvery gray, crystalline transition metal<http://en.wikipedia.org/wiki/Transition_metal> are intermediate between rhenium <http://en.wikipedia.org/wiki/Rhenium> and manganese <http://en.wikipedia.org/wiki/Manganese>. It would be at least an evidence for WL theory. -- Daniel Rocha - RJ [email protected]
