Effective nuclear chargePeriodic trend

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Changes in effective nuclear charge contribute to trends in size, ionization, affinity, and bonding across a period.

How to interpret this relation type

The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.

Electronic-structure calculationPeriodic trend

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

Electronic-structure calculations help decompose periodic trends while remaining dependent on Hamiltonian, basis, correlation, and relativistic treatment.

How to interpret this relation type

A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
