Does helium have a high melting point

WebPlatypuskeeper • 11 yr. ago. Well, the fact that helium boils at a lower temperature than hydrogen implies that there are weaker intermolecular forces between the helium atoms than between hydrogen molecules. There's only one force in question here, which is the London force, since they're both non-polar. Which makes the theory rather simple ...
