The photoelectron spectra above show the energy required to remove a 1selectron froma nitrogen atom and from an oxygen atom.
which of the following statements best accounts for the peak in the upper spectrum being to the right of the peak in the lower spectrum?
a. nitrogen atoms have a half-filled psubshell.
b. there are more electron-electron repulsions in oxygen atoms than in nitrogen
c. electrons in the psubshell of oxygen atoms provide more shielding than electrons in the psubshell of nitrogen atoms.
d. nitrogen atoms have a smaller nuclear charge than oxygen atoms.
