- Ytterbium is an element of the periodic table with an atomic number of 70, discovered by Jean de Marignac in the year 1878. The element is named after Ytterby, Sweden.
- It is a white silvery, soft, ductile and rare earth metal.
- It is attacked by the strong acids and reacts slowly with cold water and air. The oxide forms a protective layer on the surface when reacted or oxidized in air.
- Physical properties of Ytterbium differ widely when compared to other elements.
- Usually, elements will have ferromagnetic and antiferromagnetic properties at low temperatures but it is paramagnetic at a temperature of 0.1 Kelvin.
- Ytterbium clocks are the World’s most stable atomic clock. A large number of atoms present in the element made the clock more stable.
- It is used as a doping agent to improve the strength, grain refinement and mechanical properties of stainless steel.
- It also acts as an industrial catalyst.
- Few alloys of Ytterbium are used in dentistry.
- Ytterbium, a silvery white metal is electropositive which reacts with water to form ytterbium hydroxide.
- Nowadays, this is element is used in the making of memory devices and tunable lasers.
