Ununoctium [1] (eka-radon or element 118) is the temporary IUPAC for the transactinide element of atomic number 118 and temporary element symbol Uuo.[2] An ununoctium atom is very unstable, meaning it quickly changes to another atom (nuclear reaction). Only three atoms of ununoctium have been produced since 2002. Although it is a noble gas, it is more reactive than other noble gases.
