Hey buddy here is ur answer !!!
》 Nitrogen has positive electron gain enthalpy whereas oxygen has negative. however oxygen has lower ionization enthalpy than nitrogen.Explain.
》 Nitrogen has a electronic configuration of 1s^2,2s^2,2p^3.
》 As the p orbital is half filled,it has an extra stability than other elements next to it.
》 The outermost electronic configuration of nitrogen is 2s22p1x2p1y2p1z.
》 It is stable because it has exactly half filled 2p-subshell.
》Therefore, it has no tendency to accept extra electron and energy has to be supplied to add additional electron.
》Thus, electron gain enthalpy of nitrogen is slightly positive.
》On the other hand, the outermost electronic configuration of O is 2s22p2x2p1y2p1z.
》 It has higher positive charge (+8) than nitrogen (+7) and lower atomic size than N.
》Therefore, it has a tendency to accept an extra electron.
》Thus, electron gain enthalpy of O is negative.
》However, oxygen has four electrons in the 2p subshell and can lose one electron to acquire stable half filled configuration and therefore, it has low ionization enthalpy.
》Because of stable configuration of N, it cannot readily lose electron and therefore, its ionization enthalpy is higher than that of O.
Hope this answer will help u !!!
