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.
