james harrington asked the Naked Scientists: Dear Dr. Chris, I'm a GCSE chemistry student (taking it through to AS and A level) and i've always been puzzled why hydrogen is in group 1 of the periodic table (with the alkali metals). I asked my teacher if hydrogen is a metal and he gave me a straight no.
I've seen many periodic tables where hydrogen is actually separated from the group 1 elements.
They could have just as easily chucked it into group 17 eh?
The one with fluorine, chlorine, bromine, iodine and astatine.
