Chapter 11, Problem 62A

Interpretation Introduction

Interpretation: The feature of energy levels of hydrogen due to which only certain values of energy are allowed is to be given.

Concept introduction: In an atom, the electrons revolve around the nucleus in levels called the energy levels.

Answer to Problem 62A

The energy levels of hydrogen atom are quantized.

Explanation of Solution

This postulate was given by Bohr in his atomic theory. It stated that energy levels in an atom are quantized due to which electrons can possess certain discrete energy values and the values in between these discrete values are not allowed. Also that each energy level can have a fixed number of electrons which is given by $2n^2$ where $n$ is the number of energy level. If an electron has to move from on energy level to another energy level, it has to gain a fixed amount of energy.

Conclusion

The energy levels of hydrogen atom are quantized.
