This is one of the newly discovered elements which was obtained in the mid 1990s in a lab of a German research facility. A group of scientists received it as a result of a nuclear reaction involving bismuth, nickel, and iron. The new element was named roentgenium, after Wilhelm Conrad Röntgen, a German scientists known for creating an X-ray technology. Roentgenium is extremely radioactive and dangerous to the living things on our planet. It does not occur naturally and is used solely in research. So far, only a few atoms of this element have been obtained by the scientists, and the production of this element does not seem to have perspectives.
