Og

Oganesson

Oganesson (Og) is a radioactive element that has the atomic number 118 in the periodic table, its appearance is not fully known due to the minuscule amounts produced of it. It is in Group 18. It has the symbol Og.

Oganesson is classed as a noble gas due to its presence in Group 18. A collaboration between Joint Institute for Nuclear Research in Dubna and the Lawrence Livermore National Laboratory produced the element in 2002. This was from the collision of calcium 48 and californium 249 n a cyclotron. After 2300 hours of acceleration two atoms of Oganesson 294 were created for 2.55 ms. The element is named after Yuri Oganesson, a Russian radioactivity research scientist.
