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.
