Question

Correct order of ionisation potential in beryllium boron carbon nitrogen and oxygen

Answer 1

Answer:

The Correct order of ionization potential in beryllium boron carbon nitrogen and oxygen:

O>N>C<B<Be

Answer 2

Correct increasing order of ionisation potential for the given elements is as follows.

   beryllium < boron < carbon < oxygen < nitrogen  

Explanation:

Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom.

When we move across a period from left to right then there occurs a decrease in atomic size of the atoms. Also, a half filled orbital of an atom is much more stable in nature. Therefore, its ionization energy is even more than an incompletely filled orbital or smaller size atom.

Hence, correct increasing order of ionisation potential for the given elements is as follows.

          beryllium < boron < carbon < oxygen < nitrogen
