Lanthanoids Contraction: Electronic Configuration, Oxidation State …
WebThe stability of oxidation state depends mainly on electronic configuration and also on the nature of other combining atom. The elements which show largest number of oxidation states occur in or near the middle of series (i.e., 4s 2 3d 3 to 4s 2 3d 7 configuration). For example, Mn exhibits all oxidation states from +2 to +7 as it has 4s 2 3d 5 ...

Lanthanides - Lanthanide Contraction, Electronic Configuration, …
WebThe most common oxidation state of ytterbium is +3, but the +2 oxidation state also occurs (which is unusual for a lanthanide). It is more reactive than the other lanthanide elements, … Ytterbium is a chemical element with the symbol Yb and atomic number 70. It is a metal, the fourteenth and penultimate element in the lanthanide series, which is the basis of the relative stability of its +2 oxidation state. Like the other lanthanides, its most common oxidation state is +3, as in its oxide, halides, and … See more Physical properties Ytterbium is a soft, malleable and ductile chemical element that displays a bright silvery luster when pure. It is a rare-earth element, and it is readily dissolved by the strong See more It is relatively difficult to separate ytterbium from other lanthanides due to its similar properties. As a result, the process is somewhat long. … See more Ytterbium was discovered by the Swiss chemist Jean Charles Galissard de Marignac in the year 1878. While examining samples of gadolinite, Marignac found a new … See more Although ytterbium is fairly stable chemically, it is stored in airtight containers and in an inert atmosphere such as a nitrogen … See more Ytterbium is found with other rare-earth elements in several rare minerals. It is most often recovered commercially from monazite sand (0.03% ytterbium). The element is also found in euxenite and xenotime. The main mining areas are China, … See more The chemical behavior of ytterbium is similar to that of the rest of the lanthanides. Most ytterbium compounds are found in the +3 oxidation … See more Source of gamma rays The Yb isotope (with a half-life of 32 days), which is created along with the short-lived Yb isotope (half-life 4.2 days) by neutron activation during … See more WebFeb 26, 2024 · Lanthanide Series are f block elements in which the differentiating electron enters into 4f orbital. Hence this series is also called the 4f series. The common oxidation state of all lanthanides and actinides is +3. Some of the lanthanides also show +2 and +4 oxidation states.
