Question

Explain the formation of bond in sodium chloride and magnesium chloride

Answer 1

Answer:

The atomic number of Na is 11, its electronic configuration is

2,8,1.

 It has 1 valence electron, so it loses 1 electron to form Na+

ion.

 The atomic number of Cl is 17, its electronic configuration is 2,8,7.

 It has 7 valence electrons, so it gains 1 electron to form Clion.

 Then, the attraction between the Na+

ion and Clion results in the

formation of sodium chloride molecule, NaCl.
