What is Flerovium?
Flerovium is a synthetic chemical element with the symbol Fl and atomic number 114. It is part of the group known as the superheavy elements, specifically located in the seventh period and the p-block of the periodic table. Flerovium is named after the Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research in Dubna, Russia, where the element was first synthesized in 1998 by a Russian-American collaboration team.As a superheavy element, flerovium does not occur naturally and is produced in a laboratory through the fusion of lighter nuclei, such as bombarding plutonium targets with calcium ions. Its most stable known isotopes have very short half-lives, on the order of a few seconds, making it challenging to study. Due to its short-lived existence, research on flerovium is primarily focused on understanding its nuclear properties and its position in the periodic table, rather than on practical applications.

Atomic Structure of Flerovium
Flerovium (Fl) is a superheavy synthetic element with the atomic number 114 on the periodic table. Named after the Flerov Laboratory of Nuclear Reactions where it was first synthesized, Flerovium’s atomic structure exhibits some fascinating characteristics that distinguish it from lighter elements. Understanding its atomic structure requires delving into its electronic configuration, nuclear composition, and predicted chemical properties, which are all influenced by its position in the periodic table and the effects of relativistic mechanics on its electrons.
Electronic Configuration
Flerovium’s electronic configuration is theorized to be [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p² placing it in the p-block of the periodic table. This configuration suggests that Flerovium may exhibit some properties similar to lead (Pb), which is directly above it in Group 14. However, due to relativistic effects, the actual chemistry of Flerovium may deviate significantly from these predictions.
Nuclear Composition
The nucleus of Flerovium atoms contains 114 protons, which defines its position as the 114th element in the periodic table. The number of neutrons in Flerovium can vary, leading to the creation of different isotopes. The most stable isotope known to date is Flerovium-289, with 175 neutrons. These isotopes are characterized by extremely short half-lives, with Flerovium-289 having a half-life of about 2.6 seconds, indicating the inherent instability of superheavy elements.
Relativistic Effects
The atomic structure of Flerovium is significantly influenced by relativistic effects. As electrons in heavy elements move at speeds approaching a significant fraction of the speed of light, their mass increases, which in turn affects their interaction with the nucleus and with each other. These effects are particularly pronounced in superheavy elements like Flerovium, leading to changes in electron orbital shapes, energy levels, and chemical reactivity.
Predicted Properties
Based on its electronic configuration and the anticipated impact of relativistic effects, Flerovium is expected to have some unique properties:
- It might display a relatively high degree of inertness, similar to the noble gases, due to the stabilization of its 7p electrons.
- Its metallic properties are predicted to be quite distinct from those of lighter group 14 elements, possibly exhibiting a lower melting point and a higher density.
- The chemical reactivity of Flerovium is largely unknown and a subject of ongoing research. Predictions suggest it might form compounds with oxygen, hydrogen, and halogens, but the stability and characteristics of such compounds remain speculative.

Preparation of Flerovium
The preparation of Flerovium, a superheavy synthetic element with the atomic number 114, involves highly sophisticated nuclear reactions conducted in particle accelerators. Flerovium does not occur naturally and can only be created artificially through the collision of lighter nuclei. The process to prepare Flerovium primarily involves bombarding a target material with accelerated ions of another element.
Key Steps in the Preparation:
- Selection of Target and Projectile: The preparation process begins with the selection of suitable target and projectile materials. For Flerovium, Plutonium (Pu) or Californium (Cf) targets have been used, with Calcium (Ca) ions acting as the projectiles.
- Acceleration: The Calcium ions are accelerated to high velocities using a particle accelerator. This step is crucial for ensuring that the ions have sufficient kinetic energy to overcome the electrostatic repulsion of the target nucleus upon collision.
- Collision and Fusion: The high-speed Calcium ions collide with the target atoms. When these ions successfully fuse with the target nuclei, new, heavier nuclei are formed.
- Detection and Identification: The atoms of Flerovium produced are highly unstable and undergo rapid radioactive decay. Detecting and identifying Flerovium involves tracking these decay events, which are characterized by the emission of alpha particles (helium nuclei). The decay patterns help scientists confirm the creation of Flerovium and study its properties.

Production of Flerovium
Flerovium, a superheavy synthetic element, is produced in highly specialized nuclear research facilities rather than being a byproduct of nuclear reactors like Technetium. Here’s an overview of its production process:
Direct Fusion with Calcium Ions
- Source: Flerovium (Fl) is produced by bombarding target atoms like Plutonium (Pu) or Californium (Cf) with Calcium (Ca) ions in particle accelerators.
- Process: When the target atoms are bombarded with high-speed Calcium ions, the nuclei can fuse, resulting in the creation of Flerovium.
- Extraction: Unlike Technetium, Flerovium cannot be “extracted” through chemical processes due to its rapid decay. Instead, its presence is confirmed by detecting the decay products characteristic of Flerovium isotopes.
Cold Fusion Reactions
- Source: An alternative method for producing Flerovium involves using lighter targets and projectiles in cold fusion reactions, though this method is less commonly used for Flerovium than for other superheavy elements.
- Process: In these reactions, a beam of lighter ions is directed at a heavy target material, aiming to achieve fusion at relatively low energies compared to hot fusion methods.
- Extraction: The identification of Flerovium follows its synthesis, relying on the detection of specific decay chains that confirm the production of Flerovium isotopes.
Applications of Flerovium
Currently, Flerovium (element 114) does not have practical applications due to its extremely short half-life and the challenges associated with producing it in sufficient quantities for practical use. As one of the superheavy elements, its existence is primarily of interest to scientific research aimed at understanding the properties of elements at the extreme end of the periodic table. Here are the potential areas of interest related to Flerovium:
