Electronic structure of states of matter

[GRB 080319B]

Is there a defined change in the electron orbitals of atoms as they transition from one state to the next? Is there a connection between the average kinetic energy of an atom, its electronic structure and its state of matter?

I know there is a connection between kinetic energy and phase, but I couldn't give you any details. I don't know about the electrons though.
