How was roentgenium discovered?
Discovery of Roentgenium Roentgenium was first made by research scientists at the Heavy Ion Research Laboratory in Darmstadt, Germany in 1994. The scientists bombarded nickel-64 with bismuth-209 in a heavy ion accelerator. The element is named after physicist Wilhelm Conrad Röntgen who discovered X-rays in 1895.

What is the history of darmstadtium?
History and Discovery Darmstadtium is a synthetic element. It was predicted by Mendeleev and was named eka-platinum and later was named as the element 110. It was created by Peter Armbruster and Gottfried Munzenberg in 1994 in GSI Helmholtz Centre for Heavy Ion Research, Germany.
What is the atomic weight of darmstadtium?
Darmstadtium. The atoms of element 110 had an atomic weight of 269 and decayed after 260 microseconds (1 microsecond = 1 millionth of a second) into atoms of hassium -265 by emitting an alpha particle ( helium nucleus). Element 110 was named darmstadtium after the German city where the GSI is located.
Are there any stable isotopes of darmstadtium?
There are no stable isotopes of darmstadtium, but a number of radioactive isotopes have been discovered. Like elements similar to it in atomic number, radioactive isotopes of darmstadtium are isolated through fusion of two atoms of different elements, or through the observable decay of heavier elements.
What is the half life of darmstadtium?
And the heaviest isotope, darmstadtium-281 has a half-life of 11 seconds, while darmstadtium-279 has a half life of 0.18 seconds. All the isotopes undergo decay through alpha decay or spontaneous fission, and none of the isotopes undergoes beta decay.
