🔹 Basic Information

• Element Name: Oganesson
• Discovered By: Joint team of Russian and American scientists (Dubna–Livermore collaboration)
• Year of Discovery: 2002 (officially named in 2016)
• Category: Noble Gas (theoretical)
• Group: 18 (Noble gases)
• State at Room Temperature: Unknown (likely a solid or very heavy gas) ❓

Oganesson is a synthetic, radioactive element — it does not occur naturally and can only be made in labs.

🔸 Chemical Properties

• Chemical Symbol: Og
• Atomic Number: 118
• Atomic Mass: ~294 u (most stable isotope, extremely short-lived)
• Valency: Unknown (likely 0 or +2)
• Electronic Configuration: [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁶ (predicted)

Og is in the noble gas group, but may not behave like typical noble gases due to its large atomic size and high reactivity.

📘 Basic Things to Know

Oganesson is the heaviest known element on the periodic table and is super radioactive, decaying in less than a millisecond. Scientists know very little about it because it disappears so quickly.

🤔 Interesting Facts

• Named in honor of Yuri Oganessian, a nuclear physicist who helped discover several superheavy elements 👨‍🔬
• Only a few atoms of oganesson have ever been made — it exists for just fractions of a second! ⏱️
• Might not be a gas like other noble gases — it may act more like a metal or semi-metal
• Predicted to be very reactive, unlike its noble gas cousins like helium and neon 💥
• It is part of the “island of stability” theory — an area of the periodic table where certain heavy elements might last longer ⚛️

🔧 Common Uses

⚠️ Oganesson has no practical uses due to its extremely short life and how hard it is to produce.

• Scientific Research Only: Used to explore the limits of the periodic table and nuclear physics 🧪
• Nuclear Chemistry: Helps scientists study how superheavy elements are made and behave 🔬
• Theoretical Models: Useful for testing quantum and atomic structure predictions 📘

📚 Conclusion

Oganesson is a superheavy, super-short-lived element that pushes the boundaries of science. For students, it shows how chemistry is still growing — and how we’re still discovering the secrets of the universe! 🌌🔍
