Draw the energy level diagram for Hydrogen atom and show transitions corresponding to lines of Lyman and Balmer series.
Answers
Explanation:
The energy level diagram of the hydrogen atom is shown in the figure above depicting different series line.
There are four series namely
1. Lyman Series (U.V.)
2 Blamer Series (visible)
3. Psachen Series (infrared)
4. Brackett Series (infrared)
5. Pfund Series (infrared)
n=principle quantum number whose values ranges from 1−∞
n=1represents the ground energy level
n=∞is the highest energy level.
1. Lyman Series (U.V.)
In this series the transition occur from n>1 to the first orbit that isn=1. This represents the Lyman Series of the Hydrogen atom.
It is mainly observed in the ultraviolet region of the EM wave.

This is further divided into sublevels as α−lymanfor n=2 and so on.
2 Blamer Series (visible)
In this series the transition occur from n>2to the second orbit that isn=2. This represents the Balmer Series of the Hydrogen atom.
It is mainly observed in the Visible region of the EM wave.

Where, n=3,4
This is further divided into sublevels as α−Balmerfor n=3and so on.
3. Psachen Series (infrared)
In this series the transition occur from n>3 to the second orbit that isn=3. This represents the Paschen Series of the Hydrogen atom.
It is mainly observed in the Infrared region of the EM wave.

4. Brackett Series (infrared)
In this series the transition occur from n>4 to the second orbit that isn=4. This represents the Bracket Series of the Hydrogen atom.
It is mainly observed in the Infrared region of the EM wave.

In this series the transition occur fromn>5to the second orbit that isn=5. This represents the Bracket Series of the Hydrogen atom.
It is mainly observed in the Infrared region of the EM wave.
