Give reasons why hydrogen resembles alkali metals?

(N/A) Hydrogen resembles alkali metals,i.e.,$Li, Na, K, Rb, Cs$,and $Fr$ of group $1$ of the periodic table in the following respects:
$(i)$ Like alkali metals,hydrogen contains one electron in its outermost orbit and exhibits a $+1$ oxidation state.
$(ii)$ Like alkali metals,hydrogen loses its only electron to form a positive ion,i.e.,$H^+$.
$(iii)$ Like alkali metals,hydrogen combines with electronegative elements such as oxygen,halogens,and sulphur to form oxides,halides,and sulphides,respectively.
$(iv)$ Like alkali metals,hydrogen acts as a strong reducing agent.
