उत्तर
Sodium chloride is formed by the complete transfer of one valence electron from a metallic sodium atom to a non-metallic chlorine atom.
- Sodium atom (Na): Atomic number is 11. Electronic configuration is 2, 8, 1. It loses 1 valence electron to attain a stable octet, forming a sodium cation (Na+).
- Chlorine atom (Cl): The atomic number is 17. The electronic configuration is 2, 8, 7. It gains that 1 electron to complete its stable octet, forming a chloride anion (Cl−).
