Cl only exists as Cl2 in nature
This occurs through how Cl is extremely attractive due to only mis singing one valence electron in its outer shell to make a full shell. So thus it creates a covalent bond with Cl2and it’s stable.

The oxidation number of chlorine can be -1, 0, +1, +3, +4, +5, or +7.

What is an oxidation number?

The total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.

The oxidation number of chlorine can be -1, 0, +1, +3, +4, +5, or +7, depending on the substance containing the chlorine. The most common oxidation numbers are -1 (as in HCl and NaCl ) and 0 (as in Cl2 ).
