New Alloy? H + Al?
« on: 26/05/2006 15:32:42 »
Is it possible since Hydrogen is a metal, to make an alloy of Hydrogen and Aluminium? Or would it make Aluminium Hydrite? Is Helium a metal?

Helium is not a metal

It is a noble gas = very unreactive

Hydrogen is not stirctly a metal
it can act as a metal or nonmetal
it can form a cation or an anion (+ or - charge)

So no you could not form alloys with hydrogen

You would probably get Aluminium Hydride AlH3

Hydrogen is believed to become metallic under very high pressures - eg in the centre of Jupiter, but nder normal circumstances it isn't metallic, although it can chemically behave a bit like one (and like a non-metal)
