Flerovium is a superheavy chemical element with symbol Fl and atomic number 114. It is an extremely radioactive synthetic element. It is named after the Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research in Dubna, Russia, where the element was discovered in 1999. The lab's … See more The heaviest atomic nuclei are created in nuclear reactions that combine two other nuclei of unequal size into one; roughly, the more unequal the two nuclei in terms of mass, the greater the possibility that the two react. The … See more Very few properties of flerovium or its compounds have been measured; due to its extremely limited and expensive production and the fact that it decays very quickly.

Facts About Flerovium Live Science
WebFlerovium was first made in Dubna, Russia in 1998. Name: Flerovium Symbol: Fl Atomic number: 114 Atomic weight: 289.19 State: presumably a solid Group, period, block: 14, 7, p Color: unknown Classification: unknown presumably post-transition metals Electron configuration: 5f14 6d10 7s2 7p2. WebFlerovium is expected to be a liquid metal due to spin-orbit coupling "tearing" apart the 7p subshell, so that its 7s 2 7p 1/2 2 valence configuration forms a quasi-closed shell similar to those of mercury and copernicium. Solid flerovium should have a face-centered cubic structure and be a rather dense metal, with a density of around 14 g/cm 3. WebFlerovium is a superheavy metal because it has 114 protons in its nucleus - more than the 112 required to be considered a superheavy metal. Flerovium was only officially added to … تفسير منام شمس
