What is the maximum number of emission lines when the excited electron

1.	What is the maximum number of emission lines when the excited electron of a H-atom in n = 6 drops to the ground state?
Answer» Number of lines produced when an electron from nth shell drops to ground state = n(n-1)/ 2 Now according to question lines produced when an electron drops from 6th shell to ground state = 6(6-1) / 2 = 15

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

Answer»

Number of lines produced when an electron from nth shell drops to ground state = n(n-1)/ 2

Now according to question lines produced when an electron drops from 6th shell to ground state

= 6(6-1) / 2 = 15
