Properties & Characteristics

Ytterbium (Yb) is a silvery-white lanthanide metal with atomic number 70. It has a complete 4f¹⁴ electron configuration, making it similar to alkaline earth metals in some respects. It exhibits +2 and +3 oxidation states. Ytterbium is relatively soft and reacts slowly with air and water.

Uses & Applications

Ytterbium is used as a dopant in optical fibres for fibre amplifiers operating at 1070 nm wavelength, important in telecommunications and laser technology. Ytterbium-based clocks are among the world's most precise atomic clocks. Its compounds are used as catalysts in organic synthesis.

Safety Information

Ytterbium compounds have low to moderate toxicity but should be handled with standard laboratory precautions. Ytterbium dust is a slight fire hazard. Waste must be disposed of as heavy metal waste.
