Hassium is a synthetic element with unknown chemical properties, though researchers believe it will behave like Ruthenium and Osmium which sit in the same group in the Periodic Table. The most stable isotope of Hassium has a half-life of 9.7 seconds - which means once it is made, it doesn't last for very long!
