백금 개요

Prized in catalysis, jewelry, and medicine, platinum (Pt) is among the most versatile of the precious metals. Element 78 sits in group 10 of period 6 in the d-block, with an atomic mass of 195.08, the electron configuration [Xe] 4f¹⁴ 5d⁹ 6s¹, and a Pauling electronegativity of 2.28. Its catalytic power drives the automotive catalytic converters that clean exhaust gases and many industrial chemical processes, while platinum-based drugs such as cisplatin are mainstays of chemotherapy. Highly resistant to corrosion and tarnish, the dense, silvery-white metal is solid at standard conditions and has long served as a store of value.
