What is the maximum number of emission lines when the excited electron of at atom in n =6 drops to the ground state? |
|
Answer» There will be 15 spectral lines emitted when the excited electron of a Hydrogen atom in n = 6 drops to the groundstate. They are 5 transitions arising out of 6 level (6->5, 6->4, 6->3, 6->2, 6->1); 4 transitions arising out of 5 level(5->4, 5->3, 5->2, 5->1) 3 transitions arising out of 4th level (4->3, 4->2, 4->1); 2 transitions arising out of the 3rdlevel (3->2 and 3->1) and 1 transition from 2->1 for a total of 15 spectral lines.We can also use the formula no.of spectral lines = n(n-1)/2.Here n=6; therefore the no. of spectral lines = 6(6-1)/2 = 30/2 = 15 lines |
