A model-dependent scale describing an atom’s tendency to attract shared electron density in a bonded environment.

This is an authored directed relation from the source endpoint to the target endpoint.
Electronegativity values form a model-dependent periodic descriptor; trends are useful but vary with definition, oxidation state, bonding environment, and relativistic effects.
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.
Electronegativity differences help rationalize bond polarity and ionic character, but lattice structure, coordination, polarization, orbital mixing, and environment prevent a sharp universal boundary.
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-periodic-tableopenstax-chemistry-2eiupac-periodic-tableThis is an authored directed relation from the source endpoint to the target endpoint.
Electronegativity differences contribute qualitative bond-polarity estimates used in molecular dipole reasoning, while geometry, charge redistribution, lone pairs, and conformation determine the resultant moment.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
