The element technetium is an "artificial" element. This odd metal has no stable isotopes, so any that existed on earth long ago has decayed and vanished. It was created in exp…eriments in the Berkeley cyclotron facility, but was isolated by a pair of Italian scientists who isolated it from materials sent them from the California facility. ( Full Answer )
Every form of technetium is radioactive and that makes it unstable.With a periodic table number of 43, it is the lowest number thathas no stable isotopes.
Technetium-99 has not been found on earth because there are no stable isotopes of Technetium because they are all radioactive. They also have a short half-life and therefore n…eed to be made in a nuclear reactor. It has been detected in some stars, but aside from that the best place to find technetium now is in nuclear reactors. ( Full Answer )
You cannot find technetium by normal means because it cannot befound freely on Earth. There are trace amounts of this syntheticelement in uranium, but most samples are found i…n laboratoryparticle accelerators. Some have been found on red giant stars. ( Full Answer )
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 ra…dioactive 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. ( Full Answer )
Having a Pauling electronegativity of 1,9 technetium is considereda medium chemically reactive element. Technetium react with oxygen, halogens, oxygen, sulfur, selenium,tellur…ium, boron, carbon etc. and can form alloys with metals. Technetium is dissolved in inorganic acids excepting hydrochloricacid. Do not make a confusion between reactivity and radioactivity. ( Full Answer )
Technetium is not really dangerous. Since doctors will often use Technetium 99 as a radioactive tracer. It may be radioactive but its decay is slow and will produce a minute a…mount of gamma rays. ( Full Answer )
Technetium react with oxygen, halogens, oxygen, sulfur, selenium, tellurium, boron, carbon etc. and can form alloys with metals. Technetium is dissolved in inorganic acids e…xcepting hydrochloric acid. The Pauling electronegativity is 1,9. ( Full Answer )
Probably not. It is a rather inert metal, and naturally exists only in tiny quantities. All technetium is radioactive, so people do not attempt to smell it or taste for reason…s of safety. ( Full Answer )
