In the photoelectron spectrum of ground-state magnesium, which statement correctly compares the peak arising from the 2p electrons with the peak arising from the 2s electrons?
(a) The 2p peak is about three times as tall and appears at a higher binding energy than the 2s peak.
(b) The 2p peak is about three times as tall and appears at a lower binding energy than the 2s peak.
(c) The 2p and 2s peaks have equal height and the 2p peak appears at a higher binding energy.
(d) The 2p peak is about half as tall and appears at a lower binding energy than the 2s peak.
