Question

why group15 elements have high ionisation potential than group16 elements?​

Answer 1

Explanation:

First ionisation energy is energy required to remove first outer most loose electron. ... In present case , electrons from p orbitals are removed . Since group 15 has symmetrical distribution of electrons due to half filled p orbitals therefore the atom of group 15 becomes more stable compared to group 16 elements.
