* Sodium (Na) has one electron in its outermost shell. It easily loses this electron to achieve a stable electron configuration like the noble gas Neon (Ne). When it loses this electron, it becomes a positively charged ion, Na+.
* Chlorine (Cl) has seven electrons in its outermost shell. It readily gains one electron to achieve a stable electron configuration like the noble gas Argon (Ar). When it gains an electron, it becomes a negatively charged ion, Cl-.
Electrostatic Attraction: Opposite charges attract. The positively charged sodium ion (Na+) and the negatively charged chloride ion (Cl-) are strongly attracted to each other due to this electrostatic force. This attraction is what forms the ionic bond between them, resulting in the formation of Sodium Chloride (NaCl), also known as table salt.
In summary: The ionic bond between sodium and chlorine is driven by the desire of each atom to achieve a stable electron configuration, leading to the formation of oppositely charged ions that strongly attract each other.
