An electron of hydrogen atom on an excited state is having energy E n = - 0 . 85 eV . The maximum number of allowed transitions to lower energy level is _______.

Correct answer

0

Step-by-step solution

Energy of n t h orbit is given by, E n = - 13 . 6 n 2 ⇒ - 13 . 6 n 2 = - 0 . 85 ⇒ n = 4 No of transition, = n ( n - 1 ) 2 = 4 ( 4 - 1 ) 2 = 6
