What type of chemical bond is present in sodium chloride?
- 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.
