Chapter 7, Problem 7.21P
Interpretation Introduction

Interpretation:

The reason Bohr’s model couldn’t predict spectra for atoms other than hydrogen is to be determined.

Concept introduction:

Bohr’s atomic model had the following postulates:

1) The electrons in atoms revolve around the nucleus in certain circular orbits. The orbits are the energy levels. The orbits closer to the nucleus are of lesser energy than the ones further from the nucleus.

2) The energy of an electron changes sharply upon transition from one energy level to another. The electrons absorb energy when the transition occurs from lower to higher orbits, whereas the release of energy in the form of radiation occurs when electrons move from higher to lower orbits. In a stationary state, an electron in an atom would not radiate energy.

3) The angular momentum of an electron moving around the nucleus is quantized. Thus the angular momentum of an electron is a whole number multiple of h/2π.
