For asking such type of questions
Welcome Nishtha
Hydrogen element has been placed at the top of group 1 ,above the alkali metal because the electronic configration of hydrogen is similar to those of alkali metal.both,hydrogen as well as alkali metal have 1 valence electron each .some hydrogen atom is very small in size,many properties of hydrogen are different from those alkali metal.
Thank u ??
Hydrogen resembles alkali metals as well as halogens
