  1. The Element Ytterbium By: Bailey Mountan

  2. Ytterbium • Atomic symbol: Yb • Atomic number: 70 • Atomic mass: 173 • Group number: none • Period number:6

  3. Physical Properties • Melting point: 1515 degrees Fahrenheit • Boiling point: 2185 degrees Fahrenheit • Liquid range: 372 K • Density of solid: 6570 Kg m-3 • Molar volume: 24.84 cm cubed

  4. Chemical Properties • It is soft • It is malleable • It exhibits a bright silvery luster • It slowly reacts with water

  5. Uses of Ytterbium • It is used for portable x-ray machines that do not need electricity • Acts as an industrial catalyst

  6. History of Ytterbium • It was discovered by Jean De Marignac • Discovered in Switzerland in 1878 • Named after the village “Ytterby” near Vaxholm in Sweden

  7. Isotopes, Allotropes and important compounds • Isotopes: 9 • Allotropes: there are none • Important compounds: fluorides, chlorides, bromides, iodides, oxidessulfides, selenides, and tellurides.

  8. Ytterbium was the first rare earth to be discovered, and is the most common of the rare earths. • It is impossible to get 100% pure Ytterbium. • It is more common than tin, bromine, uranium, and arsenic. • Ytterbium metal (99.9% pure) costs about $360 per kilogram. (as of 2/8/2004)
