Atomic Number:68 Symbol:Er Atomic Weight:167.26 Discovery:Carl Mosander 1842 or 1843 (Sweden) Electron Configuration: [Xe] 4f12 6s2 Word Origin:Ytterby, a town in Sweden (also the source of the name of the elements yttrium, terbium, and ytterbium)
Erbium was one of three elements found in "yttria" that Mosander separated from the mineral gadolinite. The three components were called yttria, erbia, and terbia. The components had similar names...Although erbium (along with several rare earths) was discovered in the mid-19th century, it was not isolated as a pure element until 1935 because the group of elements had such similar properties....Although a rare earth, erbium is not all that rare. The element is the 45th most abundant in the Earth's crust, at a level of about 2.8 mg/kg. It is found in seawater at concentrations of 0.9 ng/LThe price of erbium is approximately $650 per kilogram. Recent advances in ion-exchange extraction are bringing the price down while increasing uses of the element drive the price up.The melting point of erbium is 159°C, the boiling point is 2863°C, specific gravity is 9.066 (25°C), and valence is 3. Pure erbium metal is soft and malleable with a bright silvery metallic luster. The metal is fairly stable in air.
Recent studies indicate erbium may help stimulate metabolism. If the element has a biological function, it has yet to be identified. The pure metal is slightly toxic, while the compounds tend to be...Erbium is used as a neutron absorber in the nuclear industry.It may be added to other metals to lower hardness and improve workability. In particular, it is a common addition to vanadium to make it softer.Erbium oxide is used as a pink colorant in glass and porcelain glaze. It is also used to add a pink color to cubic zirconia.Erbium occurs in several minerals, along with other rare earth elements. These minerals include gadolinite, euxenite, fergusonite, polycrase, xenotime, and blomstrandine. Following other purification processes, erbium is isolated from similar elements into the pure metal by heating erbium oxide or erbium salts with calcium at 1450 °C in an inert ar...

Oct 11, 2020 · A chemical property is a characteristic of matter that can only be observed and measured by performing a chemical reaction or chemical change. In other words, you have to change the chemical identity of a substance or rearrange its internal structure to know its chemical properties.
Exothermic and endothermic reactions. The changes in energy that occur during a chemical reaction can be seen by examining the changes in chemical bonding. This can be used to classify...
Feb 13, 2017 · As students start to gradually improve their CER skills, teachers should work in relatively easy science examples like Francesco Redi’s famous investigation of spontaneous generation. My own use of this example can be found in the supporting information at the bottom of this post.
