🔹 Basic Information

• Element Name: Roentgenium
• Discovered By: GSI Helmholtz Centre for Heavy Ion Research, Darmstadt, Germany 🇩🇪
• Year of Discovery: 1994
• Category: Transition Metal / Superheavy Element
• Group: 11 (same group as copper, silver, gold)
• State at Room Temperature: Unknown (likely solid) ❓

Roentgenium is a man-made, synthetic element created in a laboratory — it does not exist naturally and has only been seen in extremely small amounts.

🔸 Chemical Properties

• Chemical Symbol: Rg
• Atomic Number: 111
• Atomic Mass: ~282 u (most stable isotope)
• Valency: Predicted: +1, +3
• Electronic Configuration: [Rn] 5f¹⁴ 6d⁹ 7s² (predicted)

Roentgenium is in the same group as gold (Au), so scientists think it might have similar metallic properties, but this is still mostly theoretical.

📘 Basic Things to Know

Roentgenium is named in honor of Wilhelm Röntgen, the German physicist who discovered X-rays 📡 — a tribute to one of the greatest scientists in history!

🤔 Interesting Facts

• Created by bombarding bismuth (Bi) with nickel (Ni) atoms in a particle accelerator 💥
• Exists for only fractions of a second before decaying into lighter elements ⏱️
• It is part of the superheavy element series at the edge of the periodic table
• Might behave like a heavier version of gold, but we don’t have enough data to confirm that
• Named to recognize Röntgen’s enormous impact on science and medicine 👨‍🔬

🔧 Common Uses

⚠️ Roentgenium has no practical or commercial uses due to its short life and limited production.

• Scientific Research: Studied in labs to understand superheavy elements and atomic decay
• Nuclear Physics: Helps scientists test theories of atomic structure and stability
• Tribute to History: Honors the legacy of a scientist who revolutionized modern medicine

📚 Conclusion

Roentgenium is a superheavy, short-lived lab-made element that expands our understanding of the periodic table. For students, it’s a reminder that even today, new elements are still being discovered, and they carry the names and legacies of great scientists. 🌟🔬
