Under extreme pressure, hydrogen is predicted to transform from a low-pressure molecular solid into an atomic solid. Several candidate structures for the atomic solid are studied as candidates for superconductivity. In particular, the 9{ital R} ({alpha}-SM) structure is found to be stable with a predicted transition temperature {ital T}{sub {ital c}}=140--170 K. Results for hexagonal phases are also discussed.
