A group of one-electron states sharing a principal-shell label, especially a common principal quantum number in hydrogenic or central-field descriptions; it is a classification of states, not a literal spherical material layer.

This is an authored directed relation from the source endpoint to the target endpoint.
In hydrogenic and central-field classifications, one-electron orbitals sharing the principal quantum number are grouped into a shell; a shell is a state classification, not a material composite.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
wp-physics-electron_shellnist-atomic-statesThis is an authored directed relation from the source endpoint to the target endpoint.
In central-field language, the principal quantum number primarily labels electron shells.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

This is an authored directed relation from the source endpoint to the target endpoint.
Shells decompose into subshells labeled by orbital angular momentum and, relativistically, total angular momentum.
The target is a member or subtype of the broader source class.
