터븀 개요

Terbium (Tb) is a soft, silvery lanthanide, element 65, in period 6 of the f-block. It has an atomic mass of 158.93, the electron configuration [Xe] 4f⁹ 6s², and a Pauling electronegativity of 1.2. The element is a key source of the green phosphors used in fluorescent lamps and color displays, and it appears in solid-state electronic devices and fuel cells. Terbium is also a component of magnetostrictive alloys that change shape in a magnetic field. Malleable and solid at standard conditions, it adopts the +3 oxidation state shared across the lanthanide series.
