Erbium - Wikipedia Erbium is a chemical element; it has 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 It is a lanthanide, a rare-earth element, originally found in the gadolinite mine in Ytterby, Sweden, which is the source of the element's name
Erbium | Uses, Properties, Facts | Britannica Erbium, chemical element, a rare-earth metal of the lanthanide series of the periodic table Pure erbium is a silvery white metal The major use of erbium is in fiber-optic telecommunications as a component of signal amplifiers in long-distance telephone and data cables
Erbium Facts, Symbol, Discovery, Properties, Uses - Chemistry Learner Erbium (pronunciation UR-bee-em [2]), represented by the chemical symbol Er [1], belongs to the family of rare earth metals [3] A mixture of six isotopes with mass numbers 162, 164, 166, 167, 168 and 170 is found in naturally occurring erbium
Element Erbium Facts - ThoughtCo 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 and properties, which became confusing Mosander's erbia later became known as terbia, while the original terbia became erbia

Facts About Erbium - Live Science Naturally occurring erbium is a mixture of six stable isotopes In addition, nine radioactive isotopes of erbium are recognized Most of the rare-earth oxides have sharp absorption bands in the
Periodic Table of Elements: Los Alamos National Laboratory Naturally occurring erbium is a mixture of six isotopes, all of which are stable Nine radioactive isotopes of erbium are also recognized Recent production techniques, using ion-exchange reactions, have resulted in much lower prices of the rare-earth metals and their compounds in recent years
Erbium - Periodic Table Erbium was discovered in 1843 by Swedish chemist Carl Gustaf Mosander, who detected it as an impurity in yttria Using ammonium hydroxide he precipitated fractions of different basicity from yttria In these fractions he found that the fraction that contained the pink color was erbium
Erbium Facts - Symbol Er or Atomic Number 68 - Science Notes and Projects Erbium is a silvery-white metallic element with the symbol Er and atomic number 68 It belongs to the lanthanide series of inner transition metals and has characteristic pink-colored compounds, especially erbium oxide Erbium finds use in lasers, nuclear technology, and fiber-optic communications Although not biologically essential, erbium compounds have emerging medical and technological uses
