Ligand-field splitting and transition-metal color

Knowledge package outline

Topic

Chemistry and matter literacy

Purpose

Explains why coordination geometry changes electronic energy levels without treating color as definitive chemical identification.

Package contents

Octahedral and tetrahedral orbital-splitting diagrams; ligand-dependent energy comparisons; absorption-color interpretation exercises; model and identification limits.

Dependencies

Electron configurations; orbital models; visible absorption concepts; paper-only examples.
