Consider the electronic confifuration of elements X,Y and Z and answer X=1s2 2s2 2px1 2py1 ; Y=1s2 2s2 2px2 2py1 2pz1 ; Z=1s2 2s2 2px1 2pz1 (i) Which element has the highest electron affinity (ii) Which element has lowest electron affinity

Solution

Dear Student,

X and Z both will have highest electron affinity as by gaining one more electron they will obtain half filled electronic configuration which is stable.
Y will have lowest electron affinity i.e. less than X and Z as no half filled or full filled stability is achieved here.

Regards,
