History

History
The element Oganesson was discovered by Joint Institute for Nuclear Research in year 2006 in Russia and United States. Oganesson derived its name from from Yuri Oganessian, physicist
The element Selenium was discovered by Jöns Jakob Berzelius in year 1817 in Sweden. Selenium derived its name derived its name from from the Greek selene, meaning 'moon'
