Question

why doesn't gold corrodes

Answer 1

Gold doesn't corrodes bcoz it is less reactive metal and doesn't reacts highly with oxygen or water etc

Answer 2

Gold Corrosion:::: Gold is the most non-reactive of all metals and is benign in all natural and industrial environments. Gold never reacts with oxygen which means it will not rust or tarnish. Gold tarnish is very thin and shows up as a darkening of reflecting surfaces.
