Where does technetium come from?

Answer 1

Technetium is now produced in nuclear reactors. Neutrons collide with atoms of uranium or plutonium to form new elements. The technetium is then converted to a compound called ammonium pertechnate (NH 4 TcO 4 ). That compound is then treated with hydrogen gas to obtain pure technetium metal.

Technetium has never been found on Earth. It has, however, been found in certain types of stars.

Answer 2

The element technetium has no stable isotopes, and will not be "mined out of the ground" because of this. It can be found in trace amounts in uranium and molybdenum ores. It is also produced as a byproduct in the fission of uranium-235 in nuclear reactors, and most of the metal that exists on earth comes from this. It can also be synthesized in the nuclear physics lab by the neutron capture of molybdenum. A sample of molybdenum is lowered into an operating nuclear reactor and bathed in the neutron flux to make technetium. A link is provided to the Wikipedia article on technetium.

Answer 3

You cannot find technetium by normal means because it cannot be found freely on Earth. There are trace amounts of this synthetic element in uranium, but most samples are found in laboratory particle accelerators. Some have been found on red giant stars.

Answer 4

Technetium is used in two main ways. The first is as a corrosion prohibitor. Little bits of it are added to steel during production. The second is

in nuclear medicine as a radioactive tracer. In this application, the radionuclide is chemically attached to a drug chosen for its tendency to collect in specific organs of the body, and the solution is then injected into the patient. After a short time (its half-life is only 6 hours), an image is collected with a radiosensitive detector for analysis.

This technique is very useful in identifying cancer metastases in locations distant from primary tumors.

Answer 5

Technetium does not exist in nature on earth. All isotopes of Tc are radioactive, and the only way to obtain these are from other radioactive isotopes of elements and nuclear fission.

Answer 6

Technetium was discovered through some lab testing in Sicily. It was discovered by Emilio Segre and Carlo Perrier in 1936. Technetium is based on the Greek word for "artificial. "

Answer 7

Technetium is an artificial chemical element and is extracted from fission products, prepared by neutron activation or by irradiation in particles accelerators.

Answer 8

Technetium may obtained: from burned nuclear fuels, in particle accelerators, by neutron activation.

Answer 9

Technetium is obtained from spent nuclear fuel. 1 gram of uranium-235 in nuclear reactors yields 27 mg of technetium-99,
