What type of chemical bond is present in sodium chloride?
Correct answer: B. Ionic bond
- A. Covalent bond
- B. Ionic bond
- C. Metallic bond
- D. Hydrogen bond
Explanation
Sodium transfers its single valence electron to chlorine, producing Na⁺ and Cl⁻ ions held together by electrostatic attraction — an ionic bond. The large electronegativity difference between the two elements is what makes the transfer, rather than sharing, favourable.

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.
