A stationary, metastable, resonance, or continuum state of the full atom, labeled by total angular momentum, parity, configuration, and other quantum numbers.

This is an authored directed relation from the source endpoint to the target endpoint.
The atom has a spectrum of bound, resonant, and continuum states.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

An atomic state can be described by its electron-configuration content, but an exact many-electron eigenstate may superpose multiple configurations, so a single configuration is generally only a label or approximation.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

Atomic configurations and levels are labeled by even or odd parity when inversion symmetry applies.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
