Position of Hydrogen:
It resembles alkali metals and also halogens . Hence it can be placed either in IA group or in VIIA
group along with halogens
Resemblances with alkali metals:
1) Hydrogen has only one electron in its valence shell, just like alkalimetals.
2) It forms monovalent cation. In this regard it resembles alkali metals.
Resemblances with halogens:
1) Hydrogen can take up one electron and can form anion H just like halogens.
2) Hydrogen has one electron short of nearest inert gas He. Halogens also have one electron short of
respective nearest inert gases.

There is no correct position for hydrogen in periodic table.Hydrogen having one electron in outmost orbital so it placed in first group.

Hydrogen can place in halogen family also because it takes one electron and get stabel helium configuration as like other halogens.

we can''t mentioned the specified postion of hydrogen in periodic table because

Hydrogen has the configuration of first A group elements so that''s why we think that it is placed in first A group elements .Hydrogen having similar properties of the seventh A group elements it has negarive charge in 7A if it takes one  electron it gets inertgas configuration

so that''s why we can''t specify the position of hydrogen in periodic table.

Thanks for asking these questions..............
