Question

when the excited electron of H atom moves from 5th shell to the lower shells the maximum number of lines obtained in UV and visible regions together is

Answer 1

Answer:

When the excited electron of an H atom in n = 6 drops to the ground state, the following transitions are possible:  

The number of spectral lines:  

2

n(n−1)

​  

 

where n=6

Hence the total number of spectral line will be:  

2

6×5

​  

=15
