Answer 2

answer : Gold


explanation:

Gold is the most non-reactive of all metals and is benign in all natural and industrial environments. Gold never reacts with oxygen (one of the most active elements), which means it will not rust or tarnish. Yet this is precisely what Russian commercial precious metal trading company, International Reserve Payment System, discovered on thousands of (allegedly) 999 gold coins "St George" issued by the Central Russian Bank (reference).
