Hydrogen

Farfoos
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.

I've read that hydrogen & flourine make a more powerful & efficient rocket propellant than Hydrogen & oxygen. That would indicate that a non-oxidized combustion is more powerful than one that's oxidized. I thought I was told combustion couldn't even occurr at all w/out oxygen-let alone be more energetic. I know there are other types of chemical reactions besides oxidation, but what kind of reaction is taking place here? I heardthe combo was rejected as rocket propellant, because the byproduct-hydroflouric acid-probably made it better for a dirty bomb than a rocket.

Does it mean that it's killing germs when it fizzes?
