What is Erbium? Definitions and examples.
Erbium is a chemical element with the symbol Er and atomic number 68. A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements on Earth. As such, it has no inherent uses except in research settings and, occasionally, as a non-radioactive “dye” for glass and other materials (which is its only major commercial application). In this article, we will explore what erbium is, where it comes from, and some of its potential uses.
What is Erbium?
Erbium is a chemical element with the symbol Er and atomic number 68. A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements on Earth. As such, it is considered a rare earth element. It is named for Ytterby, a village in Sweden.
Erbium’s principal uses involve its pink-colored erbia alumina crystal, which is used as a dopant in glasses and other materials to confer a rose color. A trivalent ion gives violet and blue colors in glasses and crystals; due to absorption of light around 474 nm by the 4f11?15d1–4f12 energy levels transition. Erbium-doped fiber amplifiers are used to amplify signals in fiber optic communications.
What is the melting point of Erbium?
Erbium is a chemical element with the symbol Er and atomic number 68. A relatively rare earth element, it is a silvery-white metal that looks similar to other rare earths. Its primary use is in fiber optic communications, as a dopant in glass and ceramic hosts for its fluorescence properties.
The melting point of erbium is 1497 degrees Celsius.
What is the boiling point of Erbium?
The boiling point of a metal is the temperature at which it melts and turns from a solid to a liquid. The boiling point of erbium is 2867 degrees Celsius.
Where is Erbium found?
Erbium is a rare earth element that is found in various minerals, including euxenite, gadolinite, and xenotime. It is also found in coal and some hydrothermal veins.
What are the properties of Erbium?
Erbium is a chemical element with the symbol Er and atomic number 68. A silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements on Earth. As such, it is a rare earth element which occurs in many minerals, usually in trace amounts.
Erbium’s properties are largely determined by the size of its atoms. The atomic radius of erbium is 195 pm and it has a metallic radius of 230 pm. These values are close to those for californium (atomic radius = 187 pm; metallic radius = 215 pm), another f-block element. The ionic radius of the Er3+ cation is even smaller at 90 pm.
Erbium’s density is 9.066 g/cm3, which is similar to that of californium (8.86 g/cm3). This value indicates that erbium atoms are relatively dense compared to other metals in the periodic table.
What are some uses for Erbium?
Erbium is a rare earth element that has a variety of uses. It is used in fiber optics, lasers, and as a dopant in semiconductors. Erbium is also used in alloys and glass making.
How was Erbium discovered?
The element erbium was first discovered in 1843 by Swedish chemist Carl Gustaf Mosander. While working with the mineral ytterbium, Mosander noticed that it contained two different impurities. He was able to isolate these impurities and name them erbia and terbia.
Conclusion
Erbium is a chemical element with the symbol Er and atomic number 68. It is a silvery-white, rare earth metal that is found in minerals such as euxenite and gadolinite. When it was first discovered in 1843, it was thought to be yttrium because of its similar properties. However, it was later determined to be a new element and given the name erbium. This element has many uses, including in fiber optics and lasers.
