Can Iron exist in the "steam" or "vapor" state? Can Helium be frozen solid? Is there enough energy to do either of these things?

Not all *compounds* can be found in all states (as they often decompose under certain conditions), but under the right conditions you can get any element into any state.

In fact, most of the periodic trends you probably learned about in general chemistry (including for metals like iron), are actually gas-phase properties. All those electron configurations they teach you? Gas phase electron configurations, not necessarily the most accurate for solid metals. All of those ionization energies and electron affinities? Those are measured for gaseous atoms as well.
