The cationic radius decreases with the increase in the:
Correct answer: D. Effective nuclear charge on the ion
- A. Number of valence shell electrons
- B. Ability of atom to lose electrons
- C. Shielding effect
- D. Effective nuclear charge on the ion
Explanation
For positively charged ions, an increase in the effective nuclear charge would decrease the cationic radius. The nucleus attracts the electrons more strongly, thus pulling them closer and decreasing the ionic radius.

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.
