Which has higher value for 1st ionisation enthalpy - oxygen or nitrogen. Why?

Text Solution

Verified by Experts

Nitrogen, due,to its stable half filled electronic cơnfiguration .2 s^2 2 p^3.. has higher first ionisation enthalpy, Removal of one .e^-. from-oxygen .2 s^2 2 p^4. requires only a less amouni of energy, as the resulting electronic configuration .2 ~s^2 2 p^1. has extra stability.
