Named after chemist Daniel Rutherford, rutherfordium is a highly radioactive metal. It has never been found naturally and only a few thousand 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 hafnium. Rutherfordium is too rare to have any commercial or industrial application. The most stable isotope of rutherfordium has a half-life of 65 seconds.
