What is Tennessine (Ts)? Discovery and synthesis of Tennessine

Introduction to Tennessine (Ts) in chemistry

Tennessine (Ts) is an artificial element in chemistry and is named after the American state of Tennessee where it was first synthesized. It is a highly radioactive element and is classified as a halogen, belonging to Group 17 of the periodic table.

Tennessine is a synthetic element, meaning it does not occur naturally on Earth and is instead created in laboratories. It was first synthesized in 2010 by a team of Russian and American scientists through the bombardment of a target with calcium ions. The resulting atom is highly unstable and rapidly decays, making it difficult to study its properties.

In terms of its atomic structure, tennessine has an atomic number of 117 and its most stable isotope has a mass number of 294. It is situated below iodine (I) on the periodic table, sharing similar chemical properties due to its location in the same group. However, due to its highly unstable nature, tennessine’s chemical properties are not well studied and understood.

Because of its radioactivity and short half-life, there are currently no known uses for tennessine. Its creation and study primarily serve to expand our knowledge of the periodic table and enhance our understanding of atomic structure and chemical properties.

In conclusion, tennessine is a synthetic element with atomic number 117. It is highly radioactive and belongs to the halogen group on the periodic table. While its chemical properties are not yet well understood, its synthesis and study contribute to the advancement of chemistry and our understanding of the elements.

Discovery and synthesis of Tennessine

The discovery and synthesis of Tennessine, element 117 in the periodic table, is a significant achievement in the field of chemistry. Tennessine was first synthesized in 2010 by a team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia.

The synthesis of Tennessine involved the fusion of isotopes of berkelium-249 and calcium-48. Berkelium-249, an element with atomic number 97, was the target material that served as the basis for creating Tennessine. Calcium-48, a stable isotope of calcium, was used as the projectile to initiate the fusion reaction.

The experiment was conducted using a particle accelerator, specifically a heavy-ion accelerator, to propel the calcium-48 ions towards the berkelium-249 target. This high-energy collision caused the fusion of the two atomic nuclei, leading to the formation of a compound nucleus. This compound nucleus underwent a series of radioactive decay processes, resulting in the creation of Tennessine.

After the initial synthesis, the resulting Tennessine atoms were highly unstable and quickly decayed into lighter elements through the emission of alpha particles. These decay processes were analyzed and confirmed by a series of detectors, including those capable of detecting characteristic alpha-particle emissions.

The discovery of Tennessine was officially recognized by the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP) in 2016. It was named after the state of Tennessee in the United States, in honor of the contributions made by researchers from the Oak Ridge National Laboratory and Vanderbilt University in the discovery of new superheavy elements.

The synthesis of Tennessine and other superheavy elements is a remarkable accomplishment, pushing the boundaries of our understanding of the periodic table. These experiments provide insights into nuclear physics, the stability of superheavy elements, and the processes by which new elements are created.

Further studies on Tennessine and its properties are ongoing, providing valuable information for theoretical models and predictions on the behavior and characteristics of superheavy elements. These experiences pave the way for future research and the exploration of even heavier and more exotic elements.
