Unununium was first discovered by a team of scientists at the Joint Institute for Nuclear Research in Dubna, Russia in 2010. It is a highly radioactive element with a very short half-life and is not found in nature but can be synthesized in a laboratory.
Unununium, which is now known as Roentgenium, has been synthesized in laboratories by bombarding bismuth-209 with nickel-64 ions. This process occurs in particle accelerators and has been done at various research institutions around the world.

It's actually the same. It's made in a laboratory, and before they name them, does everyone have the number in latin as name. Unununium is latin for one one one. That means unununium is the old name, so i recommend you to use Roentgenium.
No food. Unununium (Uuu) Is radioactive & artificial. It is present in 0% in humans. It has also been given a final name: Roentgenium(Rg).
The atomic number of unununium (Uuu) is 111.The atomic weight of Uuu is 272 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
Unununium is a synthetic element and its properties have not been fully studied. Based on its position in the periodic table, it is predicted to be a solid at room temperature.
Roentgenium (also called unununium) is classified in the metals.
I think it is element Uuu, which has the name unununium.
Unnilquadium Unnilpentium Unnilhexium Unnilseptium Unniloctium Unnilennium Ununnilium Unununium Ununbium
Roentgenium is named after the German physicist, Röntgen (English: Roentgen). This name was proposed by the GSI Team. Before this, it was know by it's IUPAC systemic nameholder: Unununium (Uuu)
so far with the research that i have done its only common in areas were nuclear reactions are common.
