Question
A sample containing atoms of C and F was analyzed using x-ray photoelectron spectroscopy. The portion of the spectrum showing the 1s peaks for atoms of the two elements is shown above. [VISUAL] Which of the following correctly identifies the 1s peak for the F atoms and provides an appropriate explanation?
A.
Peak X, because F has a smaller first ionization energy than C has.
B.✓ Correct
Peak X, because F has a greater nuclear charge than C has.
C.
Peak Y, because F is more electronegative than C is.
D.
Peak Y, because F has a smaller atomic radius than C has.
