Consider the following neutral electron configurations in which n has a constant value. Which configuration would belong to the element with the most negative electron affinity, [tex]E_{ea}[/tex]?
a. 2s²
b. 2s² 2p²
c. 2s² 2p⁵
d. 2s² 2p⁶
The most negative electron affinity is observed for the group that has the has the greatest ability to accommodate an electron forming a negative ion. The best in this regard are elements of group 17.
