* Electronegativity: Chlorine has a relatively high electronegativity, meaning it has a strong attraction for electrons.

* Similar electronegativity: When two chlorine atoms bond, their electronegativities are the same. This means they have an equal pull on shared electrons.

* Covalent Bonding: Instead of an electron being transferred (ionic bond), the electrons are shared equally, resulting in a covalent bond. This creates a diatomic chlorine molecule (Cl₂).

In summary: Chlorine atoms bond covalently to form Cl₂ molecules, not ionically.
