What is it used for?
Technetium is highly radioactive and is only found naturally on the earth's crust. It can be created by bombarding molybdenum-98 with neutrons. Technetium is commercially produced as a byproduct from nuclear reactors and from the detonation of nuclear weapons. Technetium-99 can be used to help perform diagnostic tests ...
Promethium is a chemical element with the symbol Pm and atomic number 61. All of its isotopes are radioactive; it is extremely rare, with only about 500-600 grams naturally occurring in Earth's crust at any given time.Promethium is one of only two radioactive elements that are followed in the periodic table by elements with stable forms, the other being technetium.

Technetium also has numerous meta states. 97m Tc is the most stable, with a half-life of 91.0 days (0.097 MeV). This is followed by 95m Tc (half-life: 61 days, 0.038 MeV) and 99m Tc (half-life: 6.04 hours, 0.143 MeV). 99m Tc only emits gamma rays, subsequently decaying to 99 Tc. For isotopes lighter than 98 Tc, the primary decay mode is ...
Technetium is a fission product of uranium and does not occur naturally, and there are no non-radioactive isotopes of Tc. Technetium-99 (half-life = 2.1 × 10 5 years), is the most common isotope found in water. The oxidized form of technetium, the pertechnetate anion (TcO 4− ), is very soluble and mobile in groundwater.
Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting …
Technetium-99m (99m Tc) is a metastable nuclear isomer of technetium-99 (itself an isotope of technetium), symbolized as 99m Tc, that is used in tens of millions of medical diagnostic procedures annually, making it the most commonly used medical radioisotope in the world.. Technetium-99m is used as a radioactive tracer and can be detected in the body by medical …

Technetium (chemical symbol Tc) is a silver-gray, radioactive metal. It occurs naturally in very small amounts in the earth's crust, but is primarily man-made. Technetium-99 is produced during nuclear reactor operation, and is a byproduct of nuclear weapons explosions. Technetium-99 can be found as a component of nuclear waste.

Atomic Number – Protons, Electrons and Neutrons in Technetium. Technetium is a chemical element with atomic number 43 which means there are 43 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 …
Technetium is a silvery-gray radioactive metal with an appearance similar to platinum, commonly obtained as a gray powder. [20] The crystal structure of the bulk pure metal is hexagonal close-packed. The crystal structure of the nanodisperse pure metal is cubic.
Radionuclides are present in groundwater at contaminated nuclear facilities with technetium-99, one of the most mobile radionuclides encountered. In situ bioremediation via the generation of microbially reducing conditions has the potential to remove aqueous and mobile Tc(VII) from groundwater as insoluble Tc(IV). However, questions remain ...

Technetium in Diagnostic Nuclear Medicine(2) 99m Tc is one of the most widely used isotopes in nuclear medicine. It is injected into the patient in the form of a saline solution of a compound, chosen because it will be absorbed by the organ under investigation, which can then be "imaged" by an X-ray camera or scanner.
