History

History
The element Flerovium was discovered by Joint Institute for Nuclear Research in year 1998 in Russia. Flerovium derived its name from from Flerov Laboratory of Nuclear Reactions, part of JINR where the element was synthesized; itself named for Georgy Flyorov, physicist
The element Astatine was discovered by Dale R. Corson in year 1940 in United States. Astatine derived its name derived its name from from the Greek astatos, 'unstable'
