Two atoms of argon would not form a chemical bond. Argon is a noble gas and belongs to Group 18 (Group 8A) of the periodic table. Noble gases have a full complement of electrons in their outermost energy level (valence shell), making them very stable. This stable electron configuration is known as an octet, meaning they have eight electrons in their valence shell except for helium, which has two electrons.
Since argon already has a complete octet, it does not readily gain, lose, or share electrons with other atoms. As a result, argon atoms do not form chemical bonds with each other or with other elements. They exist as individual atoms, and their interactions are governed by weak intermolecular forces, such as van der Waals forces.
It's important to note that chemical bonding involves the sharing, gaining, or losing of electrons between atoms to achieve a stable electron configuration. Noble gases, including argon, have stable configurations and do not typically participate in chemical bonding.
