Question
Consider the figure in Chapter 7 of your textbook which shows the periodic trends in electron affinity.  When you look across a period (row),  why are the electron affinities of the Group 4A elements more negative than the electron affinities of the Group 5A elements?
Group of answer choices
The ratio of bonding radius to first ionization energy is smaller in 4A
Atomic radii of the Group 4A elements are bigger than their corresponding group 5A elements
Group 4A elements are more electronegative than the elements of Group 5A
Group 5A half-filled p-subshells discourage the addition of an electron
None of these choices explain the question
