Question

which one has more ionization energy in nitrogen and oxygen atoms​

Answer 1

Explanation:

Oxygen isalready unstable relative to Nitrogen, by losing one electron it attains a stable half filled orbital. So oxygenundergoes ionisation at a relatively lower energy. This is why nitrogen hasa higher ionisation energy than oxygen.

Answer 2

Nitrogen ($\text{N}_2$) has more ionisation energy when compared to Oxygen ($\text{O}_2$)

Explanation:

Find - which one has more ionisation energy among nitrogen and oxygen

• The Periodic table can helps us to find the ionisation energy.
• In a periodic table, on moving from left to right, there is a increase in nuclear charge and atomic number.
• From this it is understood, that the valence electrons are attracted by the nucleus tightly.
• An atom is considered to be very stable when they have fully filled or half filled orbital when compared with other orbital.

• $\text {Electronic configuration of Nitrogen is} \ 1s^2 \ 2s^2 \ 2p^3$

• $\text {Electronic configuration of Oxygen is} \ 1s^2 \ 2s^2 \ 2p^4$

• Nitrogen having half filled orbital, obviously it is stable.
• Hence nitrogen requires higher amount of ionization energy to get ionized.

• $\text{The ionization energy of Nitrogen is} 1402.3 \ kJ \ mol^{-1}$

• $\text{The ionization energy of Oxygen is}\ 1313.9 \ kJ \ mol^{-1}$

Therefore, Nitrogen having more ionization energy when compared with the ionization energy of oxygen.
