I just started an electronics course today and they started off by 
covering the basics like Atomic Electron Theory. One of the things
the taught was that the electrons in the outer most shell were called
the valence electron. If there was one valence electron, the element
was a conductor, if there was four, the element was a semiconductor,
and if there was 8 valence electrons, the element was an insulator. 
Thats fine, then they went to a periodic table of elements and
started talking about the Group I elements (those with one valence
electron), they mentioned Cu, Ag, and Au.

They question i have is what about Hydrogen. It has one valence
electron, is Hydrogen gas conductive? If it is, how would you measure
it? I remember from a long time ago when i used to read a lot there
was an article in Scientific American (when it was a good mag) about 
Metallic Hydrogen, it has been so long i can't remember how it was
created or anything. Is this the state where Hydrogen is conductive?
How is Metallic Hydrogen created?

The Teacher said jokingly to give him a report on it. Too bad that the
local public libraries are a intellectual dead zone. Does someone have
a paper handy they could send me that i could use, along with any info
i can get from the net, to creat a report on the conductivity of Hydrogen
and the creation and properties of metallic Hydrogen?

Are the rest of the Group I elements conductive as well?
