$\therefore$  $n = 2$

કોણીય વેગમાન $ = \,\,\frac{{nh}}{{2\pi }}\,\, = \,\,\frac{{2h}}{{2\pi }}\,\, = \,\,\frac{h}{\pi }\,$

ઉર્જા $ = \,\,\frac{{ - 2{\pi ^2}m{e^4}{z^2}}}{{{n^2}{h^2}}}\,\, = \,\,\frac{{ - 2{\pi ^2}m{e^4}{{(3)}^2}}}{{{{(2)}^2}\,({h^2})}}\,\,{\text{[ Li }}$ માટે ${\text{Z  =  3]}}$$ = \,\,\frac{{ - 9{\pi ^2}\,m{e^4}}}{{2{h^2}}}$
