Exceptions to the trend of increasing first ionization energy and increasingly negative (i.e., more favorable) electron affinity occur in group 15 elements. What is the reason for this? options: A) Removing an electron from a group 15 element would result in it having only two valence electrons B) Group 15 elements attain a noble gas configuration by adding or removing one electron C) Adding an electron to a group 15 element would result in it having four valence electrons D) Group 15 elements attain an unstable "halogen electron configuration" by adding or removing one electron E) Removing or adding an electron to group 15 elements would disrupt their three half-filled p-orbital configurations
