Consider the electronic structure of the element bismuth.
a) The first ionization energy of bismuth is Ei1 = +703 kJ / mol. What is the longest possible wavelength of light that could ionize an atom of bismuth?
b) Write the electronic configurations of neutral Bi and Bi+ cation.
c) What are the n and l quantum numbers of the electron removed when Bi is ionized to Bi+?
d) Would you expect element 115 to have ionization energy greater than, equal to, or less than that of bismuth? Explain.
The solution is provided in an attachment, with a-c answered equationally and d) answered with an explanation.
