Question 256: Atoms & Nuclei

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 represent :

Accepted Answer

In transition A, hydrogen atom comes from higher energy state n = $$\infty$$ to lower energy state n = 1. Hence, transition A represents series limit of Lyman series. In transition B, hydrogen atom comes from higher energy state n = 5 to lower energy state n = 2. Hence, transition B represents 3rd line of Balmer series. In transition C, hydrogen atom comes from higher energy state n = 5 to lower energy state n = 3. Hence, transition C represents 2nd line of Paschen series.
Hence, option (c) is correct.

Answer

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

Answer

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

Answer

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

Answer

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