The shielding effect _ from left to right in a period.
Correct answer: C. Remains the same
- A. Decreases
- B. Increases
- C. Remains the same
- D. Fluctuates
Explanation
Across a period, the number of shells remains the same. The shielding effect is between the outer electron and the nucleus, hence, the more the shells the more the shielding effect. As the number of shells remains the same, the shielding effect remains the same.

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.
