alleryStart learning →Group 16 elements have lower ionisation enthalpy than Group 15 because Group 15 has what?
ALarger atomic radius
BHalf filled p orbitals
CLower nuclear charge
DMore quantum shells
Answer & Solution
Correct answer: B. Half filled p orbitals
Half filled p orbitals in Group 15 are extra stable, so removing an electron there needs more energy.
