Flerovium is a superheavy radioactivechemical element with a very unstable electron configuration. It is most likely a poor metal meaning it melts at a lower temperature than transition metals. Flerovium was first synthesized in a Russian laboratory in 1998. The created element only lasted seconds, enough to prove it exists but not enough time to study it. While Flerovium has no practical everyday use, it is an important step in our knowledge of its properties and bonding of heavy elements. Although it may not serve a purpose to us it is an important task to learn and experiment with elements to possibly help us in the future. Working with these superheavy elements will help us will further developments in chemistry.

Flerovium Uses

Properties

The physical properties or appearance of Flerovium are not yet know because of its short half life. In addition although not much of its chemical properties are known much has been predicted as a results of several experiments. While not confirmed it is believed that Flerovium is a solid at room temperature. Between the seconds of the lifetime of a Flerovium atom scientists are unable to successfully measure the density of Flerovium. Because it's a heavy element and the great amount of electrons it is probable that Flerovium is quite dense.[1] While physical characteristics are not know it is probable that Flerovium has a silvery metallic because of it's position in the periodic table. [2]

Flerovium has an extremely short half life as a result of how large it is. The expressive amount of electrons in Flerovium result in an unstable condition. 24494Pu is bombarded with 4820Ca to form Flerovium 289 (289114Fl) which only has a half life of 30 seconds. Flerovium 289 emits alpha partials till it decays into element 112 Copernicium. Flerovium 288 (288114Fl) on the other hand has a half life of only 2 seconds. 285114Fl is a byproduct of the decay of 289116Lv lasting only 0.58 milliseconds. As a result of the fast decay rates of Flerovium it is extremely difficult to capture much solid information about the element.[2]

Synthesis

Machinery used for the creation of Flerovium

Because Flerovium is such as heavy element it can not exist naturally because of it's instability. It can be only created artificially by the bombardment of atoms. Only three atoms of Flerovium were ever created by the bombardment of Calcium and Plutonium atoms. The difficulty in creating Flerovium is that it requires 5 billion billion (5 x 1018) atoms of Calcium to bombarded with Plutonium to produce only one Flerovium atom. This resulted in a 40 day long project just to create a single atom of Flerovium.[1]

Even after an atom of Flerovium is created it usually lasts a maximum of only several seconds. While Flerovium 289 (289114Fl) only has a half life of 30 seconds, Flerovium 288 (288114Fl) has an even small half life of 2 seconds. Flerovium can not only be formed by the bombardment of Calcium and Plutonium atoms but also as a byproduct of the decay of element 118 Copernicium. Because Flerovium has such short half lives and is so complex to create it is probable that Flerovium will only exist in laboratories.[2]

Uses

Scientists of Joint Institute for Nuclear Research

Because Flerovium is a synthetic and radioactive element that lasts only seconds it can not be used for everyday purposes. So far it has only been used as a research topic for scientists. By studying this element scientists can learn more about the way atoms work and bond. Because of this synthesis of Plutonium and Calcium scientists have gained knowledge about how heavy elements work and bond. As a result of the difficulties of making Flerovium it will most likely only be used for scientific reasons and nothing more in the future.[3]

History

In 1998 Flerovium was first synthesized in Dubna, Russia at the Joint Institute for Nuclear Research. Flerovium 289 was created by the bombardment of plutonium ions with calcium ions. This isotope they created only had a half life of 21 seconds.[4] This is the only time an atom of Flerovium was create by the bombardment of plutonium andh calcium. The other few times Flerovium was created as a byproduct of the decay of other heavier elements. Flerovium was named after the Flerov Laboratory of Nuclear Reactions (also known as the Joint Institute for Nuclear Research). Georgiy N. Flerov is the founder of the Flerov Laboratory of Nuclear Reactions in which the element was synthesized.[2] In 2012 the IUPAC (International Union of Pure and Applied Chemistry) officialy renamed from ununquadium to Flerovium in honor of the laboratory it was created in.[5]

Flerovium is a synthetic element that was discovered in 1999. It is an extremely heavy and highly radioactive element.

History and Discovery

Dmitri Mendeleev predicted the presence of element 114 and it was named eka-lead. Flerovium was synthesized team of physicist led by Yuri Oganessian working in Joint Institute of Nuclear Research (JINR), Dubna, Russia in 1999 [1]. They bombarded plutonium-244 with calcium-48 nuclei and produced a single atom of flerovium-289. Long before its discovery, isotopes of flerovium were predicted to lie in the island of stability (elements from copernicium (112) to oganesson (118)) and with magic number of protons and neutrons, 114 protons and 184 neutrons, after helium-4, oxygen-16, calcium-48 and lead-208 which are the other members of the doubly magic atomic numbers group. It has proposed that the nuclei flerovium would be oblate and deformed which would attribute to its resistance to spontaneous fission. And in 1972, it was proposed that flerovium-298 would have a half-life of around a year. The name of the newly discovered element was confirmed as flerovium by International Union of Pure and Applied Chemistry in 2012, after the Flerov Laboratory of Nuclear Reactions of JINR, Russia. The laboratory was named after a Russian physicist, Georgy Flyorov [1]. Its symbol is Fl.

Occurrence

Flerovium is an artificial element and does not exist in nature. Around 90 atoms of flerovium have been made so far.

Physical Characteristics

Flerovium

Flerovium is predicted to be a gas at room temperature. Flerovium is expected to be present in the carbon group (Group 14) along with silicon, tin, germanium and lead. Its boiling point is lower than other members of group 14, around -60 °C. and the melting points is also low, i.e. 70 °C. Flerovium crystallize in a cubical structure that is face-centered. In solid form, flerovium is an extremely heavy element and would have a density of 14 or 22 g/cm3 [2].

Chemical Characteristics

The outermost shell of flerovium is filled and thus makes it a noble (inert) metal. It has no electron affinity. The first ionization energy of flerovium is expected to be the highest among its group. And its electronegativity would also be higher than lead. It is also the heaviest member of the periodic table. Other members of carbon group form stable compounds with +4 oxidation state but flerovium is expected to be most stable at an oxidation state of +2 and 0 [2]. Due to its short life span and relativistic effects, the chemical and physical characteristics of this element are yet to be determined.

Significance and Uses

  • Flerovium does not have any industrial applications is used for research purposes.

Health Hazards

Flerovium is a radioactive element and requires special precautions with handling and storage.
