Technetium (Tayler Carter)

  1. 1.  Technetium was mistakenly reported as having been discovered in 1925. At this time, it was named masurium. The element was actually discovered in 1937 by C. Perrier and Emilio Gino Segre in Italy. The origin of the name Technetium comes from the Greek technetos, artificial.
  2. 2.  Technetium is a solid at room temperature. The color of technetium is silver/gray. Melting point: 2200°C Boiling Point: 4877°C Density: 11.5 g.cm-3 at 20°C Technetium is one of only two elements that has no stable isotopes; all of them are radioactive. Some isotopes are produced as uranium fission products.
  3. 3.  Technetium was the first artificially produced element. It was created by bombarding molybdenum atoms with neutrons. Today, this is still how we produce technetium. When molybdenum captures a neutron, it decays into technetium. The cost of technetium is around $60 per gram.
  4. 4.  Technetium-99 is used in many medical radioactive isotope tests. Technetium-99 has also been proposed for use in optolectric nuclear batteries. One of Techntiums more useful uses is as a radioactive tracer that can be distributed throughout the body.
