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, 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 is a chemical element with symbol Er and atomic number 68. Classified as a lanthanide, Erbium is a solid at room temperature. [Xe]6s 2 4f 12. J.C. Slater, J Chem Phys, 1964, 41 (10), 3199-3205. DOI:10.1063/1.1725697.

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.

Erbium is a bright, soft, malleable, silvery-white metal. It is one of the rare earth metals. The metal slowly tarnishes in air, reacts slowly with water and dissolves in acids.
