Why do Group 16 elements have lower ionization enthalpy values compared to Group 15 in the corresponding periods?

Options

  1. AThey have more electrons in the outermost shell
  2. BThey have extra stable half-filled s orbitals
  3. CThey have extra stable half-filled p orbitals electronic configurations
  4. DThey have fewer protons in the nucleus

Correct answer

C. They have extra stable half-filled p orbitals electronic configurations

Step-by-step solution

The paragraph explains that Group 16 elements have lower ionization enthalpy values compared to Group 15 due to the extra stable half-filled p orbitals electronic configurations in Group 15.
