Erbium
Erbium is a chemical element with the symbol Er and atomic number 68. It was discovered by Carl Gustaf Mosander in Ytterby, a town in Sweden. Erbium is one of the so called rare -earth elements on the lanthanide series, is found in the minerals mentioned under dysprosium. In 1842 Mosander separated "yttria" found in the mineral gadolinite, into three fractions which he called yttria, erbia, and terbia. The names erbia and terbia became confused in this early period. After 1860, Mosander's terbia -
