Answer:

C

Explanation:

For sodium to bond with chlorine, it is through electrovalent bonding.

It means , one electron is transferred from the sodium to the chlorine.

Normally, chlorine has 17 electrons, by adding one , we get 18 electrons.

This is the number of electrons for Argon

The chlorine electron configuration will be like:

C. Argon

Bonding of sodium with chlorine:

When sodium ion reacts with chlorine ion if forms sodium chloride. Sodium looses one electron forming sodium cation while chlorine gains an electron forming chloride anion. Thus in this order they both attains stable electronic configuration. For sodium to bond with chlorine, it is through electrovalent bonding.

So,  the chlorine electron configuration will be like argon since it has 18 electrons that is noble gas configuration.

Thus, correct option is D.
