Hydrogen is the first element in the periodic table. It has Is1 configuration. It shows resemblances with Alkali metals of Group-I as it has ns1 configuration. It has tendency like them to form H+ ion.
Like Halogens group 17, it has tendency to gain one electron and acquire inert gas configuration. As it shows resemblance with group I and group 17, its position is anomalous.
