Hydrogen is considered to be in a group of its own. -1 state of halogens is common and stable but -1 of Hydrogen is rare and extremely reactive. Still, If I'd be Moseley I'd place it above the alkali metals. Metallic hydrogen was discovered in 1996. Its +1 oxidation state is much stable like the others. Other properties are much similar. The only discrepancies here are electronegativity and covalency.

Hey all, Great forum! Loved all the discussions here Now, I went through a research paper from RSC where they have Reduced CO2 and Water to CO and H2 gas via Solar energy. Is this really feasible in the long run? Because, the Products or Syn Gas is used to make Gasoline via the Fisher Tropsch process. So that would mean unlimited fuel right without global warming, right? Also, to add, it used a Ruthenium Complex. That could be a downer. Isn't Ruthenium way expensive?
