The metal which does not react with oxygen under ambient conditions.
Answer to Problem 1CQ
The metal which does not react with oxygen under ambient conditions is Gold.
Explanation of Solution
Metals gets oxidized when they reacts with oxygen under ambient conditions. In ambient air there is presence of moisture which results in corrosion of material. Moisture in air reacts with metals and corrodes it in the presence of oxygen.
For a metal to prevent itself from corrosion and oxidation the metal must have a very stable electron configuration to prevent reaction with oxygen molecules. The metal also be placed in least reactive list in periodic table and must have chemically inert in nature.
From the above listed requirements only gold matched with all the properties. Gold exhibits all of the listed properties.
Conclusion:
Thus, the metal which does not react with oxygen under ambient conditions is Gold.
