Information @ a Glance

  • Technetium is the chemical element and has atomic number 43 and it is the lowest atomic number element without any stable isotopes and TC is the symbol of technetium.
  • It is  most uses for a radioactive tracer that can be distributed throughout the body. All technetium is produced synthetically and only minute amounts are found in nature.
  • It was predicted long before it was actually discovered and it is a silvery gray transition metal that is naturally found in uranium ore.
  • The common oxidation states of technetium are +7, +5, and +4. Under oxidizing conditions technetium will exist as the pertechnetate ion, TcO4-.It was the first element to be produced artificially.
  • Appearance of technetium is clear and colourless solution.
  • The medical isotope technetium could be made in hospitals rather than nuclear reactors and it is a man-made radioactive isotope manufactured from the element technetium.
  • The element technetium is extremely hard to find, and even harder to keep hold of.
  • It provides several opportunities for complex formation with a large number of different ligands, and its oxidation state can change from +1 up to +7.
  • The structure of technetium complexes can also be characterized by the coordination number (N), which can vary from 4 to 7, allowing tetrahedral, tetragonal pyramidal , octahedral, capped octahedral or pentagonal bipyramidal geometry.
