I heard of a proposed propulsion system for intersteller travel called a Bussard Ramjet. This was to use thin gasses in the intersteller realm as fusion fuel for the reactor in its engines. Because intersteller hydrogen is so rarified, it was supposed to magnetically draw it into its inlet. When I read this, I wondered how anything non-metal could react to a magnetic field. Afterall, hydrogen's a gas. Then I realized that gas is a state of matter-not a chemistery of matter. Can hydrogen qualify as a metal w/ a superdooperdooperscooper low vaporizing temp? Is iron a gas w/ a superdooperpooperscooper high "freezing" temp? Is hydrogen attractible to a mag-field? What criteria qualifies a metal? I know mercury's a metal that melts at room temp.
