Sodium Chloride is not a covalent compound. Sodium and Chlorine do not form any covalent compounds exclusively with each other. Sodium Chloride is an ionic compound. I'm not going to go into too much detail, but generally speaking, any compound between a metal and a non-metal will be ionic. This is because most metals have a tendency to lose electrons in order to form stable positive ions and non-metals have an affinity to gain electrons in order to form stable negative ions. Once these ions have formed due to the transfer of electrons from the metal to the non-metal, the ions are left attracted to one another because of their differing charges. That electrostatic attraction is the basis of the ionic bond, whereas covalent bonds are characterized by two or more atoms sharing the same shell of electrons simultaneously. Covalent bonds are normally only seen in compounds between non-metals.

The another angle we can predict the nature of bonding that is ELECTRINEGATIVITY DIFFERENCE. Now we see the reaction of NaCl . The elcrongativiy value of Na according to PAULI'S TABLE ,IS .93 and the Cl E.N value is 3.16 .So , 3.16 - .93 =2.23 . In this way the nature of NaCl is pure IONIC COMPOUND.
