Solutions

Chapter 6, Problem 18PS

(a)

Interpretation Introduction

Interpretation The total number of emission lines, if only four quantum levels are considered has to be determined.

Concept introduction:

  • Electronic transitions that take place in excited H atom is,

    Lyman series: electronic transitions take place to the n=1 level and it is in ultraviolet region.

    Balmer series: electronic transitions take place from n>2 to the n=2 level and it is in visible region.

    Ritz-Paschen series: electronic transitions take place from n>3 to the n=3 level and it is in infrared region.

    Brackett series: electronic transitions take place from n>4 to the n=4 level.

    Pfund series: electronic transitions take place from n>5 to the n=5 level

(b)

Interpretation Introduction

Interpretation The transition of the photons emitted with lowest energy has to be identified.

Concept introduction:

  • Electronic transitions that take place in excited H atom is,

    Lyman series: electronic transitions take place to the n=1 level and it is in ultraviolet region.

    Balmer series: electronic transitions take place from n>2 to the n=2 level and it is in visible region.

    Ritz-Paschen series: electronic transitions take place from n>3 to the n=3 level and it is in infrared region.

    Brackett series: electronic transitions take place from n>4 to the n=4 level.

    Pfund series: electronic transitions take place from n>5 to the n=5 level

As the energy gap between two transition states increases the frequency of the radiation emitted also increases (E=hν)

(c)

Interpretation Introduction

Interpretation The transition of the photons emitted with lowest wavelength has to be identified.

Concept introduction:

  • Electronic transitions that take place in excited H atom is,

    Lyman series: electronic transitions take place to the n=1 level and it is in ultraviolet region.

    Balmer series: electronic transitions take place from n>2 to the n=2 level and it is in visible region.

    Ritz-Paschen series: electronic transitions take place from n>3 to the n=3 level and it is in infrared region.

    Brackett series: electronic transitions take place from n>4 to the n=4 level.

    Pfund series: electronic transitions take place from n>5 to the n=5 level
