What is Ruthenium?

Ruthenium, the forty-fourth element on the periodic table, is a hard, silvery-white transition metal. It's a rare member of the platinum group, prized for its durability.

Atomic Number: 44

Symbol: Ru

Atomic Mass: 101.07 u

Category: Transition Metal (Platinum Group)

State at Room Temperature: Solid

Discovered By: Karl Ernst Claus (1844)

⚛️ Atomic Structure of Ruthenium

Ruthenium has forty-four protons, fifty-seven neutrons (in its most common isotope, Ruthenium-102), and forty-four electrons, with eight in its outer shell.

  • 🟢 Protons: 44
  • 🔴 Neutrons: 57 (Most common isotope, Ruthenium-102)
  • 🟡 Electrons: 44

💡 Did you know? Ruthenium-106 is used in eye cancer treatment due to its beta radiation!

🔬 Ruthenium Properties

Ruthenium is hard, brittle, and resistant to corrosion. It melts at 2334°C (4233°F) and is chemically inert, similar to platinum.

🧪 How Was Ruthenium Discovered?

In 1844, Russian chemist Karl Ernst Claus isolated Ruthenium from platinum ore residues in the Ural Mountains, naming it after "Ruthenia" (Latin for Russia).

⚡ Uses of Ruthenium

  • 💾 Electronics: Hard disk drives and resistors.
  • ⚗️ Catalysis: Ammonia production and chemical reactions.
  • 🏭 Alloys: Strengthens platinum and palladium.
  • 🩺 Medicine: Ruthenium compounds in cancer research.

💡 Fun Facts About Ruthenium

  • 🌍 One of the rarest elements in Earth's crust.
  • 🪙 Part of the platinum group metals.
  • 🇷🇺 Named after Russia (Ruthenia).
  • ✨ Adds shine to jewelry alloys.

⚠️ Safety & Precautions

Ruthenium is non-toxic in solid form, but its compounds (like ruthenium tetroxide) are volatile and toxic. Handle with gloves and ventilation.
