Draw a neat labelled diagram of an atom with energy levels . Write the maximum
number of electrons in each energy level.
Answers
Answer:
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.
λ1=R(121−n21)
Wheren=2,3
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.
λ1=R(221−n21)
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.
λ1=R(321−n21)
