What is argon melting and boiling point?
What is argon melting and boiling point?
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.
What is argon boiling point in Kelvin?
87.3 K
Argon is extracted industrially by the fractional distillation of liquid air in a cryogenic air separation unit; a process that separates liquid nitrogen, which boils at 77.3 K, from argon, which boils at 87.3 K, and liquid oxygen, which boils at 90.2 K.

Why does argon have a low boiling point?
Argon is monatomic – it exists as separate atoms. There are are van der Waals’ forces between its atoms. The melting and boiling points of these elements are very low because: van der Waals’ forces are very weak forces of attraction …
What is the state of argon?
noble gas
Classified as a noble gas, Argon is a gas at room temperature.
What is the configuration of AR?
[Ne] 3s² 3p⁶Argon / Electron configuration
Why does argon have a low melting point?
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.
