Per NCERT, how is SODIUM CHLORIDE (NaCl) formed at the atomic level?
ANa loses 1 electron → Na⁺ (with stable Ne config); Cl gains 1 electron → Cl⁻ (with stable Ar config); Na⁺ and Cl⁻ are then held by electrostatic attraction
BNaCl is held by nuclear forces
CNa and Cl form a covalent bond
DNa and Cl share an electron pair
Answer & Solution
Correct answer: A. Na loses 1 electron → Na⁺ (with stable Ne config); Cl gains 1 electron → Cl⁻ (with stable Ar config); Na⁺ and Cl⁻ are then held by electrostatic attraction
Per NCERT §9.4.2 + Fig 9.13, NaCl = ionic compound from electron transfer + ionic bond.
