if you want to make a strong battery, should you pair two metals with high electron affinities, low electron affinities, or a mix? explain your answer.

Explanation:

A strong battery requires one metal that easily donates electrons (low electron affinity, acts as anode) and one that easily accepts electrons (high electron affinity, acts as cathode). A mix allows for electron flow and redox reaction. High - high would lack electron donor, low - low would lack electron acceptor.

Answer:

A mix. One metal (low electron affinity) donates electrons (oxidation at anode), another (high electron affinity) accepts electrons (reduction at cathode), enabling electron flow and battery function.
