2 step solution
Problem 3
What information is provided by an electron configuration?
3 step solution
Problem 5
Is it possible to deduce the electron configuration for an atom from its photoelectron spectrum? If so, describe how. If not, describe why not.
4 step solution
Problem 6
We will now construct two possibilities for the photoelectron spectrum of \(\mathrm{K}\). a) First, consider the first three shells (18 electrons) of \(\mathrm{K}\). For these 18 electrons, estimate the IEs [Hint: compare to Ar.] and indicate their relative intensities. b) If the \(19^{\text {th }}\) electron of \(\mathrm{K}\) is found in the \(n=4\) shell, would the ionization energy be closest to \(0.42,1.4\), or \(2.0 \mathrm{MJ} /\) mole? Explain. [Hint: compare to Na and Li.] Show a predicted photoelectron spectrum based on this assumption.
