Question

Give reason the first ionisation enthalpy of group 15 is higher than group 16

Answer 1

Answer:

Half filled or completely filled orbitals are more stable than partially filled orbitals . Since group 15 elements have more stable nuclei ,therefore to remove electron from it will require more energy compared to group 16 elements. Thus , first ionisation enthalpy of group 15 will be higher than group 16 elements

❤⭐...REASON:-...⭐❤

• ❤.. Due to extra stable half filled ${p}$ orbitals electronic configuration of Group 15 elements, larger amount of energy is required to remove electrons compared to Group 16 elements.
