23 Aug 2013 Instead of microwaves, this new pair of clocks uses lasers to excite the atoms. And instead of cesium, it uses ytterbium, a rare metal named after

For a wider selection of files connected with Ytterbium, see Category:Ytterbium. Ytterbium. Ytterbium is a soft, malleable and rather ductile element that exhibits a bright silvery luster.A rare earth, the element is easily attacked and dissolved by mineral acids, slowly reacts with water, and oxidizes in air. What is YTTERBIUM? Ytterbium is a chemical element with symbol Yb and atomic number 70. It is the fourteenth and penultimate element in the lanthanide series Ytterbium is an element with the symbol Yb and the atomic number 70. It is a metal, variously described as either silvery or slightly yellowish, that is quite reactive yet stable in air.

Ytterbium, named after a Swedish village, is another soft and bright silvery metal with various applications. Ytterbium-169 is a radiation source for portable X-ray machines and it is also used in nuclear medicine. Ytterbium is doped to stainless steel to enhance its mechanical properties. Ytterbium-169 | Yb | CID 105164 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety Se hela listan på en.wiktionary.org An atom of Ytterbium in the gas phase, for example, gives off energy when it gains an electron to form an ion of Ytterbium. Yb + e – → Yb – – ∆H = Affinity = 50 kJ/mol. To use electron affinities properly, it is essential to keep track of sign. When an electron is added to a neutral atom, energy is released.

Specific heat capacity: 0.15 J/gK.

It can be alloyed with stainless steel to improve some of its mechanical properties and used as a doping agent in fiber optic cable. Ytterbium has the lowest boiling point of the rare-earth metals. The element has little practical use beyond research. Radioactive 169 Yb isotope is a source of hard X-rays useful in portable radiographic devices. It is used as a dopant in a variety of optical materials, including lenses. Ytterbium has few uses. It can be alloyed with stainless steel to improve some of its mechanical properties and used as a doping agent in fiber optic cable where it can be used as an amplifier.
