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.
OverviewAI-generated
Erbium is a chemical element with the symbol Er and atomic number 68. Its standard atomic weight is 167.26, and it has an electronegativity of 1. The element was discovered in 1879. In chemical notation, it is represented by the canonical SMILES string "[Er]" and the Unicode character "鉺".
