The nuclear reaction to obtain roentgenium is:
Bi-209 + Ni-64 = Rg-272 + n
The first nuclear reaction used to obtain roentgenium was: 20983Bi + 6428Ni = 272111Rn + 1 n
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)
Roentgenium (AN = 111) was found by a team led by Sigurd Hofmann in 1994. In 2001, his discovery was deemed to have insufficient evidence, but subsequent confirmation in 2002 led to the formal recognition in 2003.
No elements were discovered in 1990. Two elements were discovered in 1994. They were Darmstadtium (atomic number 110) and Roentgenium (atomic number 111). Copernicium was discovered in 1996 and Fleroovium was discovered in 1999.
