Question

when the electrons of hydrogen atom return to L shell from shells of higher energy, we get a series of line in the spectrum. This series is called(B) Paschen series(C) Balmer series(D) Lyman series(A) Bracket series​

Answer 1

Answer:

when the electrons of hydrogen atom return to L shell from shells of higher energy, we get a series of line in the spectrum. This series is called balmer series

Answer 2

Answer:

When the electrons of hydrogen atom return from L shell from shells of higher energy, the series of line is called Balmer series.

Therefore, the option (C) is correct.

Explanation:

For the hydrogen atom, we have five types of series on the basis of transitions to different energy levels.

1. Lyman series :- The electron return from higher energy level (n₂=2, 3, 4, 5.......) to lower level (n₁=1) or K-shell.
2. Balmer series: The electron will return from higher level (n₂= 3, 4, 5.......) to lower energy level (n₁=2) or L-shell.
3. Paschen series:- The electron will return from higher energy level (n₂= 4, 5 ,6 , 7,.......) to lower energy level (n₁=3) or M-shell.
4. Brackett series​:- The electron will return from higher energy level (n₂= 5 ,6 , 7,.......) to lower energy level (n₁=4).
5. Pfund series:-  The electron will return from higher energy level (n₂= 6 , 7, 8, 9,.......) to lower energy level (n₁=5).

Therefore, when electron will return from higher level to L shell, the series of line will be Balmer series in the spectrum of hydrogen atom.
