Question

how can we represent sodium chloride (NaCl) in electron dot structure?

Answer 1

Answer: Sodium chloride  is an ionic compound formed by the transfer of electrons from sodium to chlorine.

Sodium atom has oxidation number of +1.

Electronic configuration of sodium:

$[Na]=1s^22s^22p^63s^1$

Sodium atom will loose one electron to gain noble gas configuration and form sodium cation with +1 charge.

$[Na^+]=1s^22s^22p^63s^0$

Chlorine atom has oxidation number of -1.

Electronic configuration of sodium:

$[Cl]=1s^22s^22p^63s^23p^5$

Chlorine atom will gain one electron to gain noble gas configuration and form chloride ion with -1 charge.

$[Cl^-]=1s^22s^22p^63s^23p^6$

In sodium chloride the one electron from sodium metal gets transferred to chlorine atom.
