No more, only one bond. Now we'll see that chlorine, BromIn and iodine forms more than one bond. But know that fluorine, the most electronegative atom, forms only one bond, and its oxidation state is negative one. For example, it forms bonds with h. It forms bonds with NA and CA, but it only forms one bond. Now let's look at chlorine. Chlorine is a diatomic gas at room temperature, just like fluorine.
