Which one of the following metals does not react with oxygen, water or acids? 

Which one of the following metals does not react with oxygen, water or acids?  Correct Answer <span style="">Au</span>

The correct answer is Au.
EXPLANATION:

  • Gold(Au) does not react with oxygen, water, or acids because it is the least reactive element in the periodic table.
  • gold is unaffected by air, water, alkalis, and all acids except aqua-regia.
  • Sodium is a highly reactive metal. It reacts with oxygen in the air at room temperature, the reaction is highly exothermic. 
  • Sodium produces hydrogen gas reacting with acids.
