Noun
Context #1 | Noun

chemical element

Technetium is a silvery-gray metallic element with the atomic number 43 and is the first element that was artificially produced. It has no stable isotopes, and all its isotopes are radioactive. Technetium is primarily used in medical imaging and has applications in the fields of nuclear medicine and radiography.

Examples of usage

  • Technetium-99m is widely used in medical imaging.
  • The discovery of technetium was a significant milestone in chemistry.
  • Scientists use technetium in radiopharmaceuticals for diagnostic purposes.

Etymology

The name technetium is derived from the Greek word 'technetos', meaning 'artificial', reflecting its status as the first artificially produced element. It was discovered in 1937 by Italian scientists Carlo Perrier and Emilio Segrรจ, who isolated it from a sample of uranium. The element's existence was predicted in the periodic table by Dmitri Mendeleev, but it was not until nearly three decades later that it was actually obtained in a laboratory setting. Technetium's most stable isotope, technetium-98, has a half-life of about 4.2 million years, and it was initially found in trace amounts within uranium ores. Its discovery contributed to the understanding of nuclear fission and the behavior of radioactive elements.
