Expert Answer
Hydrogen has an electronic configuration of 1s1. Its electronic configuration is similar to the outer electronic configuration ns1 of alkali metals which belong to the first group of the periodic table, and like halogens (with electronic configuration ns2np5 ) it is short by one electron to the corresponding noble gas configuration, helium 1s2.
