Question

In the given figure, the energy levels of hydrogen atom have been shown along with some transitions marked A, B, C, D and E.

The transitions A, B and C respectively represents

Options

• The series limit of Lyman series, third member of balmer series and second member of paschen series.

• The first member of the Lyman series, third member of Balmer series and second member of paschen series.

• The ionization potential of hydrogen, second member of Balmer series and third member of Paschen series.

• The series limit of Lyman series, second member of Balmer series and second member of Paschen series.

Answer 1

The series limit of Lyman series, third member of balmer series and second member of paschen series.

Explanation:

For transition A,

n₁ > 5

n₂ = 1

Hence, it is the series limit of lyman series.

For the transition of B,

n₁ = 5

n₂ = 2

Hence, it represents the third member of balmer series.

For the transition C,

n₁ =5

n₂ = 3

Hence, it represents the second member of paschen series.
