Answer 1

Though hydrogen is a non-metal, it has been placed at the top of group 1 above the alkali metals because its electronic configuration is similar to alkali metals i.e. (have 1 valence electron in the outermost shell). But while discussing the alkali metals, hydrogen is not considered. Thus, hydrogen occupies a unique position in Modern periodic table.
