A nuclide in a specified nuclear energy state that is radioactive, identified by proton number, mass number, and state where required.
wp-chem-radiochemistryiaea-neutron-activation-analysisiupac-gold-bookEach relation below ends at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
A radionuclide is an unstable nuclide and may be an isotope of a specified element; the classification depends on proton and neutron numbers and nuclear state, not chemical behavior alone.
The target is a member or subtype of the broader source class.
wp-chem-radiochemistryiaea-neutron-activation-analysisiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
Radiochemistry follows chemical identity and speciation while nuclear state and decay determine radioactive behavior.
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
wp-chem-radiochemistryiaea-neutron-activation-analysisiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
Decay-series evidence required nuclides with different masses and radioactivities to occupy the same chemical element position.
The source experiment, observation, anomaly, or problem materially motivated the development, revision, or acceptance of the target concept. Historical influence is not logical derivation; the edge detail states the documented role and avoids retrospective origin myths.
wp-chem-soddynobel-soddy-1921Each relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
A radionuclide is characterized in part by its decay modes, half-life, nuclear state, and daughter products.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
wp-chem-radiochemistryiaea-neutron-activation-analysisiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
A radioactive decay chain is described by the identities, decay modes, branching fractions, and half-lives of its parent and daughter radionuclides, while chemical separation can change which members are retained in a sample.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
wp-chem-radiochemistryiaea-livechartiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
Radiometric dating applies a decay and material-history model to radionuclide measurements; radioactivity alone does not guarantee a valid date.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
wp-chem-radiochemistryiaea-neutron-activation-analysisiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
A selected radionuclide is a material component of a radiopharmaceutical, joined to formulation and often a targeting vector; decay properties, dosimetry, purity, stability, and biology govern use.
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.
