Question

The correct order of first ionization potential of carbon nitrogen oxygen and fluorine is

Answer 1

Answer:

C<O<N<F

Explanation: left to right in periods ionisation energy increases. But nitrogen having high ionisation energy compare to oxygen due stable half filled electronic configuration of nitrogen.

Answer 2

The correct increasing order of first ionization potential will be as follows.

       oxygen < carbon < fluorine < nitrogen

Explanation:

• Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom. Atomic number of nitrogen is 7 and its electronic configuration is $1s^{2}2s^{2}2p^{3}$.

• As p-orbital of nitrogen is half-filled. So, more energy is required to add an electron into it. Therefore, ionization energy of nitrogen will be very high. Atomic number of carbon is 6 and its electronic configuration is $1s^{2}2s^{2}2p^{2}$. To attain stability it will readily accept electrons.

• Atomic number of oxygen 8 and its electronic configuration is $1s^{2}2s^{2}2p^{4}$. Atomic number of fluorine is 9 and its electronic configuration is $1s^{2}2s^{2}2p^{5}$. Also, fluorine is more electronegative in nature so, it will not easily lose an electron.
