[Question & Answer] Choose the element with the more negative (more exothermic) electron affinity from each of…..
Expert Answer
choose the element with the more negative (more exothermic) electron affinity from each pair:
Part A: Na and P are in same period (3 rd ). As we move from left to right, electron affinity increases.
As Na is in left with respect to P, the electron affinity of Na is less than P.
So, Na has more negative electron affinity.
Part B:
Na has higher electron affinity than H.
So, Na has more negative electron affinity.
Part C: P has more negative electron affinity.
