Each relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
- Relation ID
nucleus_to_alpha_particle- Relation type
- Physical constitution / realization
composition - Direction
- source β target
- Endpoint roles
- source: Constitutes / realizes; target: Constituted / realized by
- Authored annotation
- two proton constituents
Authored explanation
An alpha particle contains two protons.
How to interpret this relation type
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.
This is an authored directed relation from the source endpoint to the target endpoint.
- Relation ID
proton_to_nucleus_precise- Relation type
- Physical constitution / realization
composition - Direction
- source β target
- Endpoint roles
- source: Constitutes / realizes; target: Constituted / realized by
- Authored annotation
- proton constituent
Authored explanation
Protons are constituent nucleons of nuclei.
How to interpret this relation type
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

- Relation ID
proton_to_deuteron- Relation type
- Physical constitution / realization
composition - Direction
- source β target
- Endpoint roles
- source: Constitutes / realizes; target: Constituted / realized by
- Authored annotation
- proton constituent
Authored explanation
The deuteron contains one proton.
How to interpret this relation type
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.
This is an authored directed relation from the source endpoint to the target endpoint.
- Relation ID
exp_proton_by_rutherford_proton_transmutation- Relation type
- Experimentally tested / supported by
experimentally-verified-by - Direction
- source β target
- Endpoint roles
- source: Experimentally tested / supported by; target: Tests / supports
- Authored annotation
- hydrogen nucleus emitted from nitrogen
Authored explanation
The transmutation experiment established the hydrogen nucleus as a recurring nuclear constituent identified with the proton.
How to interpret this relation type
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.
