Darmstadtium
Element 110 · Transition Metal
Darmstadtium is the group 10 transactinide, expected to resemble platinum. First produced in 1994 at GSI Darmstadt, only a handful of atoms have ever been detected, decaying within milliseconds. No chemistry experiments have been performed; all properties are predicted, with essentially no experimental data. Darmstadtium is extremely radioactive, decaying within milliseconds.
