Facts about roentgenium

Here are a few interesting facts about the roentgenium element.

  1. Roentgenium was given its name to honor the physicist Wilhelm Rontgen.
  2. Peter Armbruster and Gottfried Münzenberg discovered the roentgenium element in the year 1994.
  3. Roentgenium is not available naturally but it is artificially made in the laboratory.
  4. Roentgenium has around 9 isotopes and all these isotopes are radioactive in nature.
  5. 282Rg is the most stable isotope of roentgenium which has a half life of only 100 seconds.

Properties of roentgenium

Here is a list of some physical properties and chemical properties of roentgenium.

  • Roentgenium is a highly radioactive element and has a very short half life.
  • The density of roentgenium is predicted between 22-24 g/cm3 and its most stable isotope has an atomic mass 282 amu.
  • Roentgenium is expected to have solid state at room temperature and pressure.
  • The crystal structure of roentgenium is BCC (predicted).
  • Roentgenium has many oxidation states, but the most stable oxidation state is +3.

Uses of roentgenium

Roentgenium is highly radioactive and it is also very rarely available. So it is not used commercially. It is generally used for research work.
