what is technetium found in
Technetium has been found in the spectrum of S-, M-, and N-type stars, and its presence in stellar matter is leading to new theories of the production of heavy elements in the stars.Technetium is a silvery-grey metal that tarnishes slowly in moist air.Until 1960, technetium was available only in small amounts.echnetium does not occur naturally in the biosphere and so normally never presents a risk. All technetium compounds should be regarded as highly toxic, largely because of its radiological toxicity. Technetium has been found in the spectra of S-, M-, and N-type stars, but is not found in earth's geosphere.
