Definition
Oganesson is the heaviest known element in the periodic table. It is a synthetic element, meaning that it has never been found in nature. It was created by scientists in Russia in 2002.
Oganesson is named after Yuri Oganessian, a Russian nuclear physicist who helped to discover it. Oganesson has the atomic number 118 and the chemical symbol Og. It is a gas at room temperature.
Oganesson is very unstable and has a very short half-life. This means that it decays very quickly into other elements. The longest-lived isotope of oganesson has a half-life of about 0.6 seconds.
Scientists are still learning about oganesson. They are not sure what its properties are, but they believe that it is a noble gas, like helium and neon.
How can the word be used?
Oganesson is a member of the noble gas family.
