🔹 Basic Information

• Element Name: Tennessine
• Discovered By: Joint Institute for Nuclear Research (Russia), Oak Ridge National Laboratory & Lawrence Livermore National Laboratory (USA)
• Year of Discovery: 2010 (officially named in 2016)
• Category: Halogen (theoretical)
• Group: 17 (Halogens)
• State at Room Temperature: Unknown (likely solid or semi-metallic) ❓

Tennessine is a synthetic element, meaning it is man-made in a lab and does not occur naturally.

🔸 Chemical Properties

• Chemical Symbol: Ts
• Atomic Number: 117
• Atomic Mass: ~294 u (most stable isotope)
• Valency: Predicted: -1, +1, +3, +5
• Electronic Configuration: [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁵ (predicted)

Tennessine belongs to the halogen group (like fluorine and chlorine), but it may not behave like typical halogens due to its heavy, unstable nature.

📘 Basic Things to Know

Tennessine was named to honor the state of Tennessee (USA), where important research was done to help discover the element. It is one of the newest and heaviest elements on the periodic table!

🤔 Interesting Facts

• Only a few atoms of tennessine have ever been created – it disappears in fractions of a second ⏱️
• It’s named after Tennessee, home to Oak Ridge National Laboratory 🇺🇸
• Might act less like a halogen and more like a metal due to relativistic effects ⚛️
• Helps scientists learn about nuclear stability and element formation 🔬
• Its discovery was part of a major international collaboration 🌍

🔧 Common Uses

⚠️ Tennessine has no practical uses because of how unstable and rare it is.

• Scientific Research Only: Used in studies of superheavy elements and nuclear chemistry 🧪
• Theoretical Chemistry: Helps in understanding how the periodic table extends beyond known elements 🧠
• Testing Physics Models: Valuable for studying atomic behavior under extreme conditions 🔍

📚 Conclusion

Tennessine is a superheavy, man-made element that offers a window into the outer limits of chemistry. For students, it’s proof that the periodic table is still growing, and there are still scientific frontiers to explore! 🌟🌌
