प्रश्न
Give reasons why hydrogen resembles alkali metals?
उत्तर
Hydrogen has electronic configuration 1s1. On the one hand, its electronic configuration is similar to that of alkali metals in the first group of the periodic table, which have an outer electronic configuration (ns1). As a result, hydrogen resembles alkali metals that lose one electron to become unipositive ions.
