Come on - helium is a noble gas, no doubt about it. (very similar chemistry to neon ;-)

Hydrogen is pretty unique though - not much point comparing its chemistry to anything else.

I would have to argue for Hydrogen being in the first column since it tends to form positively charged ions like lithium, sodium, potassium, rubidium and cesium do. Also, I believe it is thermondynamically more favorable for it to be H+ than it is H-. Hydrogen is not very electronegative like the halogens are, and is not likely to have a negative dipole when a part of a big molecule.

and that's why some periodic tables put Hidrogen to a very special place like this...

Ya, most the tables put hydrogen on the same column as iron or titanium (that is, they regard it as an transition metal!)
