Question

draw a figure showing the formation of sodium chloride molecule with its electrone​

Answer 1

Answer:

Atomic number of Sodium(Na) atom is 11.

Electronic configuration is :

Na = 2, 8, 1

So it contains 1 valence electron. In order to achieve the nearest noble gas configuration, it loses one electron to form Sodium ion.

Na

+

=2,8

Atomic number of Chlorine(Cl) atom is 17.

Electronic configuration is :

Cl = 2, 8, 7

So it contains 7 valence electron. In order to achieve the nearest noble gas configuration, it gains one electron to form Chloride ion.

Cl

−

=2,8,8

An Ionic bond is formed between sodium ion and chloride ion by complete transfer of electron from sodium to chlorine.
