Which of the following best describes the relative positions and areas of valence-electron peaks compared with core-electron peaks in a typical photoelectron spectrum of a main-group element?
(a) Valence peaks appear at lower binding energy and have smaller peak areas than core peaks.
(b) Valence peaks appear at higher binding energy and have larger peak areas than core peaks.
(c) Valence peaks appear at lower binding energy and have larger peak areas than core peaks.
(d) Valence peaks appear at higher binding energy and have similar peak areas to core peaks.
