A greater shielding effect corresponds to _ ionization energy value.
Correct answer: C. Lesser
- A. Greater
- B. Zero
- C. Lesser
- D. Variable
Explanation
The shielding effect is the repulsion between inner-shell and outer-shell electrons. A greater shielding effect means the inner electrons are more effective at blocking the nuclear charge from the valence electrons, making them easier to remove and thus lowering the ionization energy.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
