Question

if the reason explains why some elements have large exothermic electron affinities, place it the box marked \ea < 0\ (ea = electron affinity). if the reason explains why some elements have near zero, zero, or endothermic electron affinities, place it in the box marked \ea > 0 or ea = 0\. items (4 items) (drag and drop into the appropriate area below) addition of one electron will create an anion with a noble gas electron configuration. the additional electron added will occupy an outer - shell p orbital. this degenerate p orbital will now be half - filled. the additional electron added will occupy a previously unoccupied, outer - shell p orbital with an incomplete p subshell. addition of one electron to a neutral atom will disrupt a noble gas electron configuration.

Explanation:

• When adding an electron creates a noble - gas electron configuration, it is highly favorable and releases energy (exothermic, EA < 0).
• When adding an electron disrupts a noble - gas electron configuration, it is unfavorable (endothermic or near zero EA, EA > 0 or EA = 0).
• When an added electron makes a p - orbital half - filled, it is relatively favorable (exothermic, EA < 0).
• When an added electron occupies an unoccupied outer - shell p - orbital with an incomplete p - subshell, it is also relatively favorable (exothermic, EA < 0).

Answer:

• EA < 0: Addition of one electron will create an anion with a noble gas electron configuration; The additional electron added will occupy an outer - shell p orbital. This degenerate p orbital will now be half - filled; The additional electron added will occupy a previously unoccupied, outer - shell p orbital with an incomplete p subshell.
• EA > 0 or EA = 0: Addition of one electron to a neutral atom will disrupt a noble gas electron configuration.
