Introduction
- Tennessine is a superheavy synthetic element with the atomic number 117 and the symbol Ts.
- It's a highly unstable element that exists for only a very brief period of time before decaying, making it difficult to study and limiting its practical applications.
- Classified as a metalloid, its exact properties are not well-known due to its instability and rarity.
Historical Background
- The discovery of Tennessine was announced in 2010 by a team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia.
- It was discovered through the bombardment of Berkelium-249 with Calcium-48 ions.
- The element is named "Tennessine" in honor of the U.S. state of Tennessee, a hub for scientific research.
Physical Properties
- Atomic weight: Approximately 294 u.
- Melting point: Unknown.
- Boiling point: Unknown.
- Density: Estimated to be around 7.1–7.3 g/cm³.
- Color: Unknown.
- State at room temperature: Presumed to be solid.
- Electrical conductivity: Not determined.
- Magnetic properties: Unknown.
- Isotopes: Known isotopes range from 287 to 294, all of which are radioactive.
- Other notable physical characteristics: Highly unstable and short-lived.
Chemical Properties
- Oxidation states: +1, +3, +5 (predicted).
- Common compounds it forms: None known.
- Notable chemical reactions: Highly unstable, undergoes alpha decay or spontaneous fission.
Abundance and Sources
- Tennessine is not naturally occurring.
- It is synthesized in labs and has never been observed in the Earth's crust or the universe.
- Common ores or other sources: Produced through particle accelerator experiments.
- Methods of isolation or production: Through bombardment of heavy actinide elements with lighter ions.
Uses and Applications
- Industrial uses: None currently known due to its instability and short half-life.
- Medical applications: None, due to its extreme rarity and instability.
- Everyday uses: None.
- Importance in biological systems: Not applicable.
Safety
- Toxicity levels: Highly radioactive, so presumed to be highly toxic.
- Precautions to handle the element: Only specialized facilities with adequate safety measures should attempt to produce or handle Tennessine.
- Storage guidelines: Not applicable due to its very short half-life.
Interesting Facts
- Tennessine is one of the few elements named after a U.S. state.
- Its discovery filled a missing spot on the 7th period of the periodic table.
- The shortest-lived isotope of Tennessine has a half-life of less than one millisecond.
Conclusion
- Tennessine is a fascinating yet mysterious element that occupies a unique position in the periodic table.
- Due to its extreme instability and radioactivity, it remains largely unstudied and its potential applications are unknown.
- Its significance lies in its contribution to scientific research and our understanding of superheavy elements. Despite its elusive nature, Tennessine remains an intriguing subject for future study in the field of nuclear chemistry.
