Questions and Answers

What is the significance of the Schroedinger theory of the one-electron atom?

It forms the foundation of the quantum mechanical treatment of all multielectron atoms, molecules, and nuclei.

What complicates the treatment of the one-electron atom compared to one-dimensional systems?

Its three-dimensional nature and the presence of two particles.

Why is the one-electron atom considered the simplest bound system in nature?

Because it consists of only a positively charged nucleus and a negatively charged electron.
