Question

Why is there a decrease in electron affinity going from lithium to sodium?

A. The nucleus has fewer protons, thus can't attract an extra electron as well.
B. There is a stronger nuclear charge, with no additional shielding electrons or number of shells.
C. Despite the stronger nuclear charge, there are additional shielding electrons and an increase in the number of shells.
D. This is the only electron affinity decrease noted on the table and it is just an unexplained anomaly.
E. There are fewer spaces in the valence shell in which to place the added electron.
