Helium
Its single electron shell is filled, making possible reactions with other elements extremely difficult and the resulting compounds quite unstable.Helium is the most difficult of all gases to liquefy and is impossible to solidify at normal atmospheric pressures.

Answer:
Helium is the noble gas which is most difficult to liquefy.
Explanation:
The single electron shell of the helium is completely filled and that's why the intramolecular bonding forces is extremely low in the helium molecules.
For this reason a huge amount energy is required for compression of those helium molecules to turn in into liquid which makes the whole process very difficult to practically execute.
