what will not react with oxygen to give acidic oxide
Answer
Non-metals typically react with oxygen to give acidic oxides, while metals react with oxygen to give basic oxides. Therefore, we are looking for a metal that will not react with oxygen to give an acidic oxide.
Noble gases, such as helium, neon, argon, krypton, and xenon, will not react with oxygen to give an acidic oxide. This is because noble gases have a complete octet and therefore do not form compounds easily.
So, the answer to the question “What will not react with oxygen to give acidic oxide?” is noble gases.
