Which of the following has the smallest size?
Correct answer: A. Al³⁺
- A. Al³⁺
- B. F⁻
- C. Na⁺
- D. Mg²⁺
Explanation
This ion has a 3+ charge, meaning it has lost three electrons. This results in a strong attraction between the nucleus and the remaining electrons, making it the smallest ion among the options.

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.
