Platinum is a precious metal used in catalytic converters, jewelry, and chemotherapy drugs. It is highly resistant to corrosion.

About Platinum

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.
