hydrogen is both an s-block and p-block element. it can be placed under 1A group and also 7A group. it can be placed under alkali metals group due to its ability to form cation. it can be placed under halogens group due to the deficiency of an electron in its valence shell. it has more similarities with halogens than with alkali metals. so the position of hydrogen in periodic table is debatable.
