The number of protons in a nucleus, determining the chemical element.
wp-physics-proton_numberiupac-nuclideiaea-livechartEach relation below ends at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Proton number counts nuclear protons.
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.
Chemical elements are defined by proton number.
The target is a member or subtype of the broader source class.

Mass number equals proton plus neutron number.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.

Moseley’s law established atomic number as nuclear charge rather than atomic-weight order.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
