Roentgenium

Located at Group 11 and Period 7 of the Periodic Table is one of the synthesized ( man made ) Super - Heavy Element that is radioactive. This is Roentgenium.

Sigurd Hofmann and his Roentgenium

First discovered in 1994 by Sigurd Hofmann and Victor Ninov leading and their scientist team at GSI. First created ( not isolated, since it is one of the man - made ( synthesised ) element ) also by Sigurd Hofmann and Victor Ninov leading and their scientist team at GSI.

GSI is Gesellschaft für Schwerionenforschung. The discovery of Roentgenium was lead by Sigurd Hofmann and Victor Ninov, leading the scientist team at GSI. Some of the members are Peter Armbruster, Gottfried Münzenber.

Because Roentgenium is one of the man - made element, so not much is known about Roentgenium, because of its short half life.However, we still know that Sigurd Hofmann and Victor Ninov leading and their scientist team bombarded the atoms of Bismuth - 209 and the ions of Nickel - 64 with a device called Linear Particle Accelerator.

Victor Ninov

Similar to all Super - Heavy element, Roentgenium's isotopes has very short half lives. It longest isotopes is just 2 minutes, which is called Roentgenium - 282, although there are 2 other unknown isotopes, which might be 5.1 minutes and 10.7 minutes. Still, the discovered Roentgenium's isotopes is too short to discover anything. So, Roentgenium's chemical properties and physical properties is almost unknown.

Roentgenium is predicted to be extremely radioactive, because it was thought that its properties might be similar to the elements of Period 7 ( Francium, Radium and Actinium )

So, in conclusion, Roentgenium is very radioactive.

How Roentgenium got its name?

Roentgenium is named after the Physicist Wilhelm Rontgen ( Also spelled as Roentgen ), the Physicist who discovered x - rays. Before Roentgenium was officially discovered, like all man - made elements, Roentgenium holds the ' Unknown ' title, named Unununium. It was only officially named Roentgenium in November 1, 2004, where the scientists at GSI suggested the name Roentgenium, in honor of the first X - ray discoverer, Wilhelm Rontgen.

Uses

Of course, like all synthesized element do, the uses of Roentgenium is currently unknown. However, we know that Roentgenium is used in labs, mostly to research for another Super - Heavy element.
