Did You Know?
It is the chemical element with the highest atomic number and atomic mass ever synthesized.
It is named in honor of the Russian-Armenian nuclear physicist Yuri Oganessian for his pioneering contributions to the research of superheavy elements.
It is one of only two elements named after a person who was still alive at the time of naming (the other being seaborgium). Yuri Oganessian is the only living person with an element named after them.
While it is placed in Group 18 with the noble gases, it is predicted to be significantly more reactive than any of them due to relativistic effects.
