An electron of hydrogen atom on an excited state is having energy $E_{n} = - 0.85 e V$ . The maximum number of allowed transitions to lower energy level is _______.

Answer:

6.00

Solution:

Energy of $n^{t h}$ orbit is given by, $E_{n} = - \frac{13.6}{n ^{2}}$

$\Rightarrow - \frac{13.6}{n ^{2}} = - 0.85 \Rightarrow n = 4$ No of transition,

$= \frac{n ( n - 1 )}{2} = \frac{4 ( 4 - 1 )}{2} = 6$
