Justify the position of hydrogen in the periodic table?

Explanation

Hydrogen resembles alkali metals in the following aspects
(i) Electronic configuration `1s^(1)` as alkali metals have `ns^(-1)`
Hydrogen forms unipositive `H^+` ion like alkali metal `Na^+,K^+`
(iii) Hydrogne forms halides (HX), oxides `(H_2O)`, peroxides `(H_2O_2)` like alkali metals `(NaX,Na_2O,NaO_2)`
Hydrogen also acts as reducing agent like alkali metals.
