The shielding effect _ from left to right in a period.
Correct answer: C. Remains same
- A. Decreases
- B. Increases
- C. Remains same
- D. No change
Explanation
Option C is correct since the number of shells remains the same across a period. There is only an increase in the number of electrons across a period. But the shielding effect which depends on the number of inner shells remains the same across a period since the number of inner shells remains the same. Option A is incorrect since it states that the shielding effect decreases across a period which is not the case. Option B is incorrect since it states that the shielding effect increases across a period which is not the case. Option D is incorrect since it states that the shielding effect shows no change when the period changes, which is not the case.

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.
