Why noble gases have low boiling point?

Answer 1

Noble gases have low boiling and melting points because they have very weak inter-atomic attractions or forces. The motions of the atoms of the noble gases must be slowed down before the weak London dispersion forces can lock the atoms into place to form a solid.

Answer 2

Simple molecules, or small molecules bonded together covalently have low boiling points due to the weak intermolecular forces of attraction between the molecules.

The weak van der Waal's intermolecular forces of attraction caused by induced dipole interactions within the molecules can easily be broken with a small amount of heat energy. Therefore it requires a low temperature to break them up from a liquid to a gas.

Answer 3

small molecules have low boiling points because small molecules experience little London force so it doesn't require lots of heat or energy to separate the ions.

Answer 4

They are all gases at room temperature and have weak inter-atomic forces of attraction. Hence have boiling point much below zero degree Celsius.
