Ununoctium facts for kids

Ununoctium (eka-radon or element 118) is the temporary IUPAC for the transactinide element of atomic number 118 and temporary element symbol Uuo. 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. No practical uses of Ununoctium are known, other than for scientifical research in labs.

• 

  Element 118 was named after Yuri Oganessian, a pioneer in the discovery of synthetic elements, with the name oganesson (Og).

• 

  Oganesson (row 118) is slightly above the "island of stability" (white circle) and thus its nuclei are slightly more stable than otherwise predicted.
