Justify the position of hydrogen in the periodic table on the basis of its electronic configuration.
(N/A) Hydrogen has an atomic number of $1$ and an electronic configuration of $1s^1$.
Because of this configuration,it shows similarities with both alkali metals (Group $1$) and halogens (Group $17$).
Like alkali metals,it can lose one electron to form $H^+$,and like halogens,it can gain one electron to form $H^-$.
Due to these dual properties,its position in the periodic table is considered anomalous,and it is often placed separately.
