Chapter 8, Problem 8.8P

Interpretation Introduction

Interpretation:

The key distinction and the factors for the distinction between sublevel energies in one electron species, such as the $\text{H}$ atom and those in many-electron species, such as the $\text{C}$ atom is to be determined. Also whether the pattern of sublevel energies in ${\text{Be}}^{3+}$ is more like that in $\text{H}$ or $\text{C}$ atom is to be explained.

Concept introduction:

The species that contain a single nucleus with a single electron is called one-electron species. Hydrogen is the only atom in the periodic table that has a single electron in the orbitals in the ground state.

The species with more than one electron is known as the multi-electron system. Examples of many-electron systems are helium and nitrogen.
