Overview
Named after Georgy Flyorov. May have unusual chemistry approaching that of noble gases. Flerovium (Fl) is an Unknown with atomic number 114, located in period 7, group 14. Most of its properties still await further experimental confirmation.
It has the configuration [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p²; its 4 outer-shell electrons drive its bonding. Under standard conditions it exists as a solid (a very low melting point); it melts near 340 K (66.9 °C), boils near 420 K (146.9 °C), has a density around 14 g/cm³.
It is widely used in Research. It is regarded as a high-hazard element, so handle it with appropriate care. It was first described by JINR in 1998. The periodic trends guide explains the underlying patterns.
