Description
Roentgenium is a highly radioactive metal. It has never been found naturally and only a few atoms have been produced in laboratories. Its chemistry and appearance are not known with any certainty, although the chemistry is believed to be similar to gold. Roentgenium is too rare to have any commercial or industrial application. The most stable isotope of Roentgenium has a half-life of a fraction of a thousandth of a second.
