Flerovium: An Introduction to a Synthetic Element
Flerovium (Fl), with atomic number 114, is a synthetic chemical element. It belongs to the p-block of the periodic table and is classified as a transactinide element. Its existence was first confirmed in 1999 at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. The element is named after the Russian physicist Georgy Flyorov, who founded the Flerov Laboratory of Nuclear Reactions at JINR.
Natural Occurrence
Flerovium does not occur naturally on Earth or anywhere else in the universe. It is a synthetic element, meaning it is exclusively created in highly specialized scientific laboratories through nuclear fusion reactions.
Synthesis in Laboratories
The production of flerovium involves bombarding heavy nuclei with other lighter nuclei in powerful particle accelerators. For example, isotopes of flerovium have been produced by colliding plutonium-244 nuclei with calcium-48 nuclei. This process is known as cold fusion or hot fusion, depending on the energy of the colliding particles and the evaporation of neutrons.
A representative nuclear fusion reaction for creating an isotope of flerovium can be written as: $^{244}{94}\text{Pu} + ^{48}{20}\text{Ca} \rightarrow ^{292}{114}\text{Fl}^* \rightarrow ^{289}{114}\text{Fl} + 3^1_0\text{n}$ This highly controlled experiment yields only a few atoms at a time. The fleeting existence and extremely short half-lives of flerovium isotopes make its study challenging.
Extraction and Industrial Use
Given its synthetic nature and extremely short half-lives (ranging from milliseconds to seconds for its known isotopes), flerovium is not extracted from natural sources. There are no industrial applications for flerovium. Its production is limited to a few atoms at a time, making it entirely impractical for any use beyond fundamental scientific research. The primary motivation for synthesizing elements like flerovium is to explore the limits of the periodic table and investigate the theoretical “island of stability,” where superheavy elements might exhibit relatively longer half-lives.
Common, Everyday Uses
Flerovium has no common, everyday uses. Due to its synthetic nature, extreme radioactivity, and extremely brief existence, it cannot be manufactured in quantities large enough or kept stable long enough for any practical application outside of a highly specialized research laboratory environment. It is not found in consumer products, industrial processes, medical applications, or any other practical real-world scenario.
Indian Context for Superheavy Element Research
While India possesses significant capabilities in nuclear physics research at institutions such as the Bhabha Atomic Research Centre (BARC) and the Variable Energy Cyclotron Centre (VECC), the specific synthesis of superheavy elements like flerovium is conducted in a very limited number of international facilities, primarily in Russia, Germany, and the United States. Indian scientists contribute substantially to theoretical nuclear physics and experimental studies of nuclear reactions. However, the direct synthesis of flerovium is not performed in India, and consequently, there are no Indian industrial uses or extraction activities related to this element.
