A physical science student is building a battery with two metal plates. The table below shows a list of metals and their electron affinity given in electron volts, eV.
Metal Electron Affinity (electron volts, eV)
Sodium − 2.71
Magnesium − 2.31
Silver + 0.80
Platinum + 1.20
The student has a silver plate. When paired with silver, which metal plate will produce a higher voltage?
Sodium
Magnesium
Silver
Platinum
