It was discovered in Helmholtz Centre for Heavy Ion Research near the city of Darmstadt, hence it is called Darmstadtium. It is extremely radioactive. The most stable known isotope is darmstadtium-281. It has a half-life of approximately 10 seconds. Darmstadtium belongs to the group 10 elements. Therefore it should behave as the heavier homologue to platinum.
