Answer :-Argon exists as single atoms. The atoms in solid argon are held together by very weak van der Waals forces. They are weaker than those in phosphorus, sulfur and chlorine because argon atoms are smaller. Little energy is needed to break them and argon has the lowest melting point in Period 3.

Argon is an inert gas in group VIII A of the periodic table with atomic number 18, an atomic weight of 39.948, and a density of 1.40 Mg/m3. In the solid state it forms an fcc crystal with a melting point of -189.4 C and a boiling point of - 185.8 C.
