a metallic chemical element (symbol Tc) with an atomic number of 43
{i} (Tc) radioactive element whose chemical behavior is similar to rhenium; used as a diagnostic tool (Chemistry)
Metallic chemical element, one of the transition elements, chemical symbol Tc, atomic number
All its isotopes are radioactive (see radioactivity); some occur in trace amounts in nature as nuclear fission products of uranium. Its isotope technetium-97 was the first element artificially produced (1937; see cyclotron). Technetium-99, a fission product of nuclear reactors that emits gamma rays, is the most-used tracer isotope in nuclear medicine. Technetium resembles platinum in appearance and manganese and rhenium in chemical behaviour. It is also used as a metallurgical tracer and in corrosion-resistant products
a crystalline metallic element not found in nature; occurs as one of the fission products of uranium
