Unformatted text preview: tightly that the wave functions of adjacent at wave functions of adjacent atoms overlap, and effectively the bonds between the atoms of one molecule become no more important than the bonds with the atoms in the next molecule: what we have is effectively a continuum of protons through which the electrons swim. This is similar to the situation in a metal, so this is termed "metallic Hydrogen". When trying to model the behaviour of Hydrogen at high pressures we can no longer use the Perfect Gas Law to describe the pressure. As atoms come closer together we have first an attractive force, due to induced charge separation effects, called the van der Waals force. It is in this regime that liquids are formed. Closer still, however, and the cores of the atoms - the nuclei - start to repel. This force is very strong and rises exponentially as the distance between them:...
