This study calculates ion size differences using bond-valence parameters and ionic radii. These calculations help understand how ions change size within similar chemical environments.

Area of Science:

  • Inorganic Chemistry
  • Crystallography
  • Materials Science

Background:

  • Understanding ion size is crucial for predicting material properties and chemical reactions.
  • Ions (atoms with non-zero oxidation states) exhibit varying sizes influenced by their electronic configuration and coordination.
  • Accurate ionic radii data is essential for modeling crystal structures and chemical bonding.

Purpose of the Study:

  • To calculate expectation values for size differences between pairs of ions.
  • To investigate the relationship between ionic size and coordination environments.
  • To provide a method for estimating ion size variations in chemical systems.

Main Methods:

  • Utilized established tables of bond-valence parameters.
  • Employed ionic radii data for various elements.
