Which of the following remains the same across a period?
Correct answer: C. Shielding effect
- A. Nuclear charge
- B. Number of electrons
- C. Shielding effect
- D. Ionization energy
Explanation
The shielding effect remains the same across a period because the number of shells is the same for each element in the period.

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.
