Source sentences:
text: As hydrogen tops the Periodic Table's alkali metal column, it has been known for a while it has the potential to be a metal, but only under extreme pressures.
text: Metastable metallic hydrogen may have potential as a highly-efficient rocket propellant, with a theoretical specific impulse of up to 1700 seconds, though a metastable form suitable for mass-production and conventional high-volume storage may not exist.
text: Because it is much more dense than ordinary hydrogen, it also has the potential of being a huge source of energy.
