금 개요

Gold (Au) has been treasured across human cultures for its enduring luster and resistance to corrosion. Element 79 lies in group 11 of period 6 in the d-block, with an atomic mass of 196.97, the electron configuration [Xe] 4f¹⁴ 5d¹⁰ 6s¹, and the highest electronegativity in its group at 2.54. Chemically inert, gold neither tarnishes nor rusts, which preserves its brilliance indefinitely and underlies its historic role as a monetary standard. Beyond coinage and jewelry, its excellent conductivity and reliability make it essential in electronic connectors and microcircuitry. A soft, dense, yellow metal, gold is solid at standard conditions.
