Why gold never tarnishes has finally been explained
Researchers have discovered that gold resists tarnishing due to atomic rearrangements on its surface that block oxygen reactions, reducing oxidation by up to a trillion-fold. This natural protective mechanism explains why gold remains shiny for centuries and could lead to more effective gold-based catalysts for industrial and clean energy applications. The finding highlights how surface atomic structure, rather than just chemistry, determines gold's durability.
Scientists have discovered that gold's surface atoms rearrange to block oxygen, preventing tarnishing.
This finding could lead to better gold-based catalysts for manufacturing and clean energy.
