Ionic bond is produced after complete transfer of ________________ ?
Correct answer: C. Electrons
- A. Nucleus
- B. Neutrons
- C. Electrons
- D. Protons
Explanation
An ionic bond forms when electrons are transferred from one atom to another, producing oppositely charged cations and anions that attract electrostatically. Nuclei, neutrons and protons are not transferred during ordinary ionic bonding. The likely mistake is choosing protons because ions carry charge, but the charge changes because electrons are gained or lost.

About Ionic and Molecular Crystals
Ionic crystals contain oppositely charged ions held by electrostatic forces, whereas molecular crystals contain discrete molecules joined by weaker intermolecular forces. Their structures explain differences in melting point, hardness, volatility, solubility and electrical conductivity, especially between solid and molten states.
