Facts about roentgenium
Here are a few interesting facts about the roentgenium element.
- Roentgenium was given its name to honor the physicist Wilhelm Rontgen.
- Peter Armbruster and Gottfried Münzenberg discovered the roentgenium element in the year 1994.
- Roentgenium is not available naturally but it is artificially made in the laboratory.
- Roentgenium has around 9 isotopes and all these isotopes are radioactive in nature.
- 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.
