Of the metals au, fe, na, and cd, which will not give up its electrons to silver (ag) in a redox reaction?

Of the metals Au, Fe, Na, and Cd, gold will not give up its electrons to silver (Ag) in a redox reaction. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

Answer : The metal gold (Au) will not give up its electrons electrons to silver (A) in a redox reaction.

Explanation :

Redox reaction : It is a type of reaction in which the oxidation and reduction takes palace simultaneously.

The general redox reaction will be,

In this reaction, X is the most reactive metal and is the less reactive metal that means the most reactive metal will lose our electrons for less reactive metals. The more reactive metal act as an oxidizing agent and less reactive metal act as a reducing agent.

According to the reactivity series, the iron (Fe), sodium (Na) and cadmium (Cd)  metals are more reactive metals than the silver metal. So, these metals will easily give up its electrons to silver in a redox reaction.

While, the gold (Au) metal is less reactive than the silver (Ag) metal. So, gold metals will not give up its electrons to silver in a redox reaction.

Hence, the metal gold (Au) will not give up its electrons electrons to silver (A) in a redox reaction.

it's all four options.
