Answer:
Electrons are transferred.
Explanation:
Ionic Bond is formed between Cation and an Anion. The formation of Cation takes place when an atom ( mainly Metal) looses electron(s). While an Anion ois formed when an atom ( mainly Non-Metal) accepts or gain electron(s).
Example:
Na + Cl → Na⁺ + Cl⁻ → NaCl
In Above reaction the valence electron of Sodium (2s¹→2s⁰ + e⁻) is transferred to the Valence Shell of Chlorine (3p⁵ + e⁻ →3p⁶) resulting in the formation of Na⁺ and Cl⁻.
