Question

A student is completing an experiment to see how using different metals in a battery will affect the flow of electrons and the voltage of the battery. The table below shows the electron affinity of four metals.

Metal E0 (Volts)
Potassium −2.93
Magnesium −2.37
Silver +0.80
Platinum +1.20

If paired with silver, which metal would result in no flow of electric charges?
Potassium
Magnesium
Silver
Platinum

Answer 1

What the other one said

Step-by-step explanation:

Answer 2

If paired with silver, the metal that would result in no flow of electric charges would be platinum because it has the same electron affinity as silver, which means that there will be no difference in potential between the two metals, and therefore no flow of electric charges.
