Technetium has an atomic number is 43 so it has 43 protons and 55 neutrons. On periodic table‚ it’s located on Group 7‚ Period 5‚ and Block d. It has an atomic mass of 98. According to Aufbau Principle and Hund’s rule the full electron configuration of Technetium is 1s22s22p63s23d104s24p64d55s2 and condensed electron configuration of Technetium is [Kr] 4d55s2. First Ionization energy of Tc is 702 kJ mol 1 and second Ionization energy is always higher so it is 1470 kJ mol 1. (Winter‚ M) Technetium

The name of the chemical element is Technetium. Tc is the symbol of Technetium in chemistry. (Also it is the symbol of the republic of Turkey which is the country that the most awesome man‚ Karl Machin‚ lives in.) Technetium has 43 protons so its atomic number is 43. It has 55 neutrons. The sum of 55 and 43 is 98 because of that 98 is the mass number of Technetium. It is in the d-block and it is a transition metal. Technetium is in the 7th group in the periodic table because it has 1 electron on

Technetium-99m‚ or Tc-99m is the world’s most widely used medical nuclear isotope for diagnostic imaging. In its name‚ the ‘m’ of 99m describes indicates the metastability of the particular radionuclide. This metastability is the ability for a certain energy state of the radionuclide to exist indefinitely until‚ whether spontaneously or because of outside factors‚ it changes to the much more stable Tc-99‚ with a half-life of over 210‚000 years. Technetium-99m is used as a radioactive tracer which

Tc-99m Tc-99m is mostly a manmade substance. However‚ Tc-99m can be found in a few places throughout the environment. The few places that Tc-99m can be found is after detonation of nuclear weapon‚ airborne emissions from a nuclear reactor‚ airborne emissions from a nuclear fuel reprocessing plant‚ and the storage of radioactive waste in a facility‚ or a facility that treats radioactive waste. Since there are few places that produce Tc-99m there is a high need for the substance and is therefore

Technetium-99 Technetium-99 (Tc-99m) is used tens of millions of times annually. Approximately 85% of diagnostic procedures in nuclear medicine use this radioisotope. Making it the most common radioisotope used in diagnosis. Technetium-99 is used as a radioactive tracer and is detected in the body by gamma cameras. Technetium-99 is produced by bombarding Molybdenum with neutrons‚ producing Molybdenum-99. This then goes through a Beta decay with a half-life of 66 hours and produces Technetium. Technetium-99

Applications of Radiopharmaceuticals Name: Lew Chien Ai Radiopharmaceuticals are formulations containing radioisotopes‚ which are use internally for therapeutic and diagnostic purposes. Radiopharmaceuticals have modernized the medical field by their ability to provide static as well as dynamic images of internal organs in a noninvasive manner as well as by offering efficacious therapy of certain diseases. Radioisotopes are extensively used in medicine for diagnosis‚ either in

isotope. Technetium-99m is made from the synthetic substance Molybdenum-99 which is a by-product of nuclear fission. It is because of its parent nuclide‚ that Technetium-99m is so suitable to modern medicine. Molybdenum-99 has a half-life of approximately 66 hours‚ and decays to Tc-99m‚ a negative beta‚ and an antineutrino. This is a useful life since‚ once this product (molybdenum-99) is created‚ it can be transported to any hospital in the world and would still be producing technetium-99m for the
