Ds Darmstadtium
Transition Metals 110 110 171 Discovery: 1994
State: Solid
This artificial element is named after the
German city of Darmstadt – the home
of the Institute for Heavy Ion Research
where this element was first produced.

Hofmann created darmstadtium by smashing

Rg Roentgenium
State: Solid
111 111 171 Discovery: 1994
Scientists believe that this metal
shares many characteristics with
precious metals, such as gold and silver.
However, its atoms break apart within
seconds, so this has not yet been confirmed.
Roentgenium was created in Darmstadt,
Germany. It was named after Wilhelm
Röntgen, the German scientist who
106 Wilhem Röntgen discovered X-rays in 1895.
