Oganesson Element in Periodic Table | Atomic Number Atomic Mass

Oganesson

Oganesson Element:

Oganesson is the last chemical element in periodic table of elements with atomic number 118. It is represented by the symbol Og. The element has been named after the Russian nuclear physicist Yuri Oganessian of American descent who played a predominant role in synthesis of a number of super heavy chemical elements in the periodic table.  The element oganesson (after seaborgium) is the second element to be named after a scientist during his lifetime in the year 2016. The chemical element oganesson had been predicted by the Danish scientist Niels Bohr in 1922 but it could be successfully synthesized after 80 years. Oganesson could be synthesized by nuclear fusion reaction of californium-248 atoms with calcium-48 ions.

Although the element oganesson has been included the 18th group of inert gases, it does exhibit more reactivity than noble gases, especially radon, due to energetic destabilization and a radial expansion of the occupied 7p-sub shell. There has been only a single confirmed isotope of organesson with mass number 294, which could not be studied in detail due to its extremely short half-life.

Uses Of Oganesson Element:

The chemical reactions of oganesson  and formation of its compounds are still under scientific research and study. Hence, no uses of oganesson have yet been identified.
