Question

A battery contains two metals that have different tendencies to attract electrons. If one is lithium with an electron affinity of −3.05, and the other is zinc with an electron affinity of −0.76, describe how the electrons will flow. Then, describe how you could make this an even stronger battery.

Answer 1

Electrons will flow from Zinc to Lithium

Step-by-step explanation:

Since lithium has an electronegativity value of -3.05, this means that it has a very strong attraction to electrons. So a element with less electronegativity (zinc) will end up having its electrons pulled away, since electrons flow from least electronegative to most electronegative.

As for making the battery stronger, we can change it so that we use different metals with an even greater difference in electronegativity.
