어븀 개요

Indispensable to global fiber-optic communications, erbium (Er) amplifies light signals in the erbium-doped fiber amplifiers that made long-distance optical networking practical. Element 68 is a lanthanide in period 6 of the f-block, with an atomic mass of 167.26, the electron configuration [Xe] 4f¹² 6s², and a Pauling electronegativity of 1.24. The same optical properties give erbium compounds a soft pink color used to tint glass and ceramic glazes, and erbium lasers are applied in dermatology and dentistry. A silvery, malleable metal, erbium is solid at standard conditions.
