Well from what I've learnt in 7yrs of chemistry. The first shell of a atom holds only 2 electrons, the next shells can hold up to 8. If the world was perfect, all atoms would have a full shell of either 8 or 2. so basically they wan't to be full. hydrogen only has 1 outer shell electron(valence) and to make 2 it needs one more :)

Most atoms want 8 valence electrons in order to fill their Octect but Hydrogen only needs to 2 in order to fill it's first shell
