What is the maximum number of emission lines when the excited electron of a H atom in `n = 6` drop to the ground state?

A

10

B

5

C

12

D

15

Text Solution

Verified by Experts

The correct Answer is:
A
Number of emission lines in the spectrum will be equal to `((n_(2)-n_(1))(n_(2)-n_(1)+1))/(2)` where `n_(2) = 5` and `n_(1) = 1`.
`:. ((5-1)(5-1+1))/(2) =(20)/(2) =10` lines.
