Comment on the following observation: E 0 for M 2+ (aq) + 2e – → M (s) (where M = Ca, Sr, or Ba) is nearly constant.

Question

Comment on the following observation: E 0 for M 2+ (aq) + 2e – → M (s) (where M = Ca, Sr, or Ba) is nearly constant., This indicates that the standard reduction potentials of calcium, strontium, and barium are similar., This is because the electronic configuration of calcium, strontium, and barium is identical., This is due to the identical atomic radii of calcium, strontium, and barium., This suggests that the ionization energies of calcium, strontium, and barium are nearly the same.
