Darmstadtium is named after the town of Darmstadt in Germany. Darmstradtium is highly radioactive, and it's longest lived isotope has a half-life of about 4 minutes. It was first made in 1994, at the Helmholtz Centre for Heavy Ion Research, by colliding nickel and lead. Other elements were also discovered at this research centre, including bohrium, meitnerium, and copernicium. Darmstradtium is (so far) the only element discovered there that has not been named after a person. So few atoms of darmstradtium have ever been made, that nothing is known about its chemistry, we don't even know what it looks like!
