Write the electronic dot structure for sodium chloride.

The atomic no. of Sodium is 11 it means it contains 11 electron which are configured in 3 energy level as 2, 8, 1

The atomic no. of Chlorine is 17 it means it contains 17 electron which are configured in 3 energy level as 2, 8, 7

The electron dot structure of Na and Cl can be written as

Na can loose one electron to complete its octate and chloride can gain one electron to complete its octate. Na form Na+ by loosing an electron and Cl form Cl- by gaining an electron. Now Na+ and Cl- get combined to form NaCl compound. Since ions are involved it is an ionic bond.
