What is unununium?

Answer 1

Nobody can know for sure, because only a few atoms of unununium have ever been synthesized, not nearly enough to be visible to the naked eye. Also, it is extremely unstable, decaying into other elements and isotopes almost instantly, so any studies of those few atoms are limited. I would guess that it would be a greyish-black blob of rock, like a lot of other elements. Only time will tell.

Answer 2

It is the element with 111 protons (and electrons). It has been named Roentgenium. It is an extremely radioactive element which has only been created in a laboratory and, since it has a half-life of just over 2 minutes, cannot be found in nature. It was first created at the GSI Helmholtz Centre for Heavy Ion Research near Darmstadt and is named after Wilhelm Roentgen, the German physicist who discovered x-rays.

Answer 3

Unununium, also known as element 111 or roentgenium, is a synthetic element that is currently not found in nature and can only be created in laboratories through nuclear reactions. It is a highly unstable element with a very short half-life.

Answer 4

Group 11.

Unununium is now renamed as Roentgenium (atomic number 111)

Answer 5

Nobody know; only four atoms were obtained !

Answer 6

Unununium was the temporary systematic element name for element #111 in the Periodic Table, discovered in Germany in 1994 and officially named roentgenium by IUPAC in November 2004.

Answer 7

not known
