Ionization energy of nitrogen compared to oxygen?
the ionization energy of nitogen is more than oxygen because it possesses half filled p orbitals which increases its stability and results in higher I.P.
Ionization energy generally increases across a period as a result of a higher nuclear charge, however there are some exceptions such as Boron which has a lower ionization energy than Beryllium (because it is in a P orbital), and Oxygen which has a lower ionization energy than nitrogen (Because ionization decreases the electron electron repulsion in its orbitals).
If nitrogen is so abundant in our atmosphere compared to oxygen why aren't there nitrogen breathing lifeforms?
Aww, so, u been worrying about Oxygen ionization energy? worry no more because your answer is here finally!! The first ionization energy of Oxygen is: O(g) + e---------- O-(g) 1st EA=1314 KJ mol-1 second Ionization energy: O-(g) + e- --------- O2-(g) 2nd EA=3388 KJ mol-1 please draw an arrow where u see (---------). Hope this may help you!!
