Atomic number 110
Darmstadtium
Transition metal
No photo: here’s why
Darmstadtium is a synthetic element made only in vanishingly small, intensely radioactive amounts - its atoms decay so quickly that no piece big enough to see or photograph has ever existed.

How dangerous is it?
Named for the German lab that first made it, this element appears only as a few short-lived atoms inside an accelerator and exists nowhere else.
- RadioactiveImmediate
Its atoms are fiercely radioactive as they break apart, but they vanish far too quickly to gather.
Observed only by remote, shielded equipment in a handful of research facilities.
How it bonds· family overview
Darmstadtium (Ds) is a synthetic super-heavy element produced one atom at a time. Its position predicts d-block transition-metal chemistry - multiple oxidation states, oxide and halide salts - but only a handful of atoms have ever existed, so the chemistry is largely inferred from group trends.
