What is Nobelium?

Nobelium, the one hundred-second element on the periodic table, is a synthetic, radioactive actinide named in honor of a scientific legend.

Atomic Number: 102

Symbol: No

Atomic Mass: [259] u (most stable isotope)

Category: Actinide

State at Room Temperature: Solid

Discovered By: Albert Ghiorso, Glenn T. Seaborg, et al. (1958)

⚛️ Atomic Structure of Nobelium

Nobelium has one hundred two protons, one hundred fifty-seven neutrons (in its most stable isotope, Nobelium-259), and one hundred two electrons, with two in its outer shell.

  • 🟢 Protons: 102
  • 🔴 Neutrons: 157 (Most stable isotope, Nobelium-259)
  • 🟡 Electrons: 102

💡 Did you know? Nobelium's discovery was debated, with rival claims from the U.S. and Soviet Union!

🔬 Nobelium Properties

Nobelium is radioactive, silvery, and dense. Its melting point is estimated at 827°C (1521°F), and it emits alpha radiation.

🧪 How Was Nobelium Discovered?

In 1958, Albert Ghiorso, Glenn T. Seaborg, and a team at Berkeley synthesized Nobelium by bombarding curium with carbon ions, though earlier claims were contested.

⚡ Uses of Nobelium

  • 🔬 Research: Studying actinide properties.
  • ⚡ Synthesis: Precursor to superheavy elements.

💡 Fun Facts About Nobelium

  • 🏅 Named after Alfred Nobel.
  • ⏳ Half-life of 58 minutes.
  • 🌍 Discovery disputed.
  • 🏭 Exists in trace amounts.

⚠️ Safety & Precautions

Nobelium is radioactive and a radiation hazard. It's only produced in minute quantities in controlled labs.
