44 Ru 루테늄 101.07 u

루테늄 개요

A rare member of the platinum group, ruthenium (Ru) is element 44, located in group 8 of period 5 in the d-block. It has an atomic mass of 101.07 and the electron configuration [Kr] 4d⁷ 5s¹, with a Pauling electronegativity of 2.2. Ruthenium is used in electronics, where thin films serve as durable electrical contacts, and in chemistry as a versatile catalyst. As an alloying agent it markedly hardens platinum and palladium, improving their wear resistance for demanding applications. The metal is solid at standard conditions and, like its platinum-group neighbors, resists corrosion and attack by most acids.
