9.1. Hydrogen has electronic configuration 1s1similar to the outer electronic configuration (ns1) of alkali metals, which belong to the first group of the periodic table. On the other hand, like halogens (with ns2np5) configuration belonging to the seventeenth group of the periodic table, it is short by one electron to the corresponding noble gas configuration, helium (1s2). Hydrogen, therefore, has a resemblance to both alkali metals, which lose one electron to form unipositive ions, as well as with halogens, which gain one electron to form uni-negative ion. Like alkali metals, hydrogen forms oxides, halides and sulphides. Howeve

5.10. We know,
PV=nRT
n = PV/RT
n= (0.1 x34.05 x 10-3)/ (0.083 x 819)
