Explain ionic bond in NaCl.

Explanation

NaCl is lormed by the combination of sodium and chlorine. An atom of sodium transfer an electron to chlorine and form sodium ion (positive ion.)
`Noverset(dot)atoNa^(+)+e^(-)`
The chlorine atom gain, one electron from sodium and form chloride ion (negative ion)
`:underset(..)overset(..)Cl+e^(-)to:underset(..)overset(..)Cl:^(-)`
Thus both `Na^(+)andCl` ions are held by electrosatic force of attraction to form ionic molecule NaCl.
