Clarification

Explanation:

Copper is actually reactive element. It can react fast with oxygen and #H_2S#. The green layer you find on the copper vessels and utensils is actually #CuO#, #Cu(NO_3)_2# or some other product of Cu.

Most stable metals are stable because on exposure to air they form a stable non-porous oxide layer on the surface of the metal. This limits the exposure of oxygen to the metal.

May be more clarity is needed on the question asked.

Hope this helps.
