Chapter 5.1, Problem 2LC

Interpretation Introduction

Interpretation: To determine the quantum mechanical model of electrons in atoms.

Concept Introduction: According to the quantum mechanical description of an atom, an electron is said to inhabit an electron shell if all of its neighbors have the same main quantum number (n) as well as principal energy level. Regions in space that have been likely to contain electrons are defined by orbitals.

Answer to Problem 2LC

The permissible energies of an electron are determined by the quantum mechanical model, as well as the probability that an electron will be found in different parts of the nucleus.

Explanation of Solution

The quantum mechanical model is as below:

• Atomic electrons have quantized energy.
• The fact that electrons behave like waves directly contributes to the existence of quantization electronic energy levels.
• It is impossible to simultaneously identify an electron's exact position as well as velocity within an atom.
