Problem
Two unknown solid samples each give a PES spectrum with exactly one valence-region peak of identical relative height (2 electrons).
• Sample A: valence peak at 9.4 eV
• Sample B: valence peak at 5.8 eV
Knowing that one sample is Mg and the other is Ca, identify which sample corresponds to each element and explain your reasoning in one sentence.
