Explanation:

In general you can have two type of compounds: Covalent ones and ionic ones.
Ionic bonds are Formed by a metal element (Na, and the elements that are on the left of the periodic table escluding H ) and a non metal element(Cl and the elements that are on the right of the periodic table)
Covalent bonds are formed by the union of non metals among them. May be tha5t the non metal is the same like Cl with Cl where the covalent character of the bond is 100%
