Singleelectronic

Single-electronic refers to an electronic configuration where an electron occupies a single energy level or orbital. This configuration is commonly observed in atoms or molecules with a low number of electrons. In a single-electronic configuration, only one electron is present in a particular orbital or energy level, which results in a relatively simple electronic structure.

In atomic physics, single-electronic systems are of significant interest due to their simplicity, which makes them ideal for theoretical studies and experimental investigations. These systems typically consist of few electrons and can be accurately described by the time-independent Schrödinger equation. Single-electronic systems are often found in certain chemical compounds or molecules where the electron configurations are such that only one electron occupies a particular orbital.

Single-electronic states have unique properties that differentiate them from multi-electronic systems. For example, in a single-electronic system, the energy is highly dependent on the potential energy of the system, and there is no stabilization due to electron-electron repulsions that typically occur in multi-electronic systems. Furthermore, single-electronic states allow for the exact computation of electronic properties, such as the expectation value of operators, without the need for approximations. These characteristics make single-electronic systems particularly relevant in the study of chemical bonding, electron scattering, and atomic physics.

Theoretical models, such as the hydrogen-like model, have been extensively studied to understand single-electronic systems. These models provide a starting point for understanding more complex systems and help to develop new methodologies for investigating electronic configurations. Research on single-electronic configurations continues to be an active area of study, with ongoing investigations into their properties and behavior in various contexts.
