Natural technetium exist only in infinitesimal traces in some uranium deposits.
Technetium is a radioactive metallic element with no known taste or flavor. It is not naturally occurring on Earth and is primarily produced in nuclear reactors.
Technetium is not a naturally-occurring element; it was created in a laboratory.
The lightest element without a stable isotope is Technetium (atomic number 43). All of its isotopes are radioactive, with none occurring naturally on Earth.
Technetium has no stable isotopes but at least 30 artificial ones have been identified.
Uranium deposits may contain infinitesimal amounts of technetium isotopes.
No, Technetium does no occur naturally on earth except in trace amounts in molybdenum deposits.
Everything in the Periodic Table up to Uranium (92). Wrong, not everything, the elements Technetium (43) and Promethium (61) do not occur naturally.
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
Out of the first 92 elements, 1 being hydrogen (H) and 92 being uranium (U), there are 90 that are naturally occurring. Technetium (Tc) and promethium (Pm) are man-made elements and do not have any isotopes occurring naturally.
Uranium is the heaviest naturally occurring actinide.
Technetium is not a naturally occurring element like uranium or plutonium but produced as a result of nuclear transformations, typically in a nuclear reactor. It has never been used in the making of nuclear weapons.
As of now, scientists recognize 118 elements in the periodic table, of which 80 occur naturally on Earth. These naturally occurring elements range from hydrogen, the lightest, to uranium, the heaviest. Some of these elements, like technetium and promethium, are radioactive and have no stable isotopes, so they are typically produced synthetically. However, the majority of naturally occurring elements can be found in various forms in the environment.
