The Chemistry of Art > Complexes
The formation of complex ions by transition metal ions increases the variety of coloured compounds that can be produced
Students learn to:
- explain what is meant by a hydrated ion in solution
- describe hydrated ions as examples of a coordination complex or a complex ion and identify examples
- describe molecules or ions attached to a metal ion in a complex ion as ligands
- explain that ligands have at least one atom with a lone pair of electrons
- identify examples of chelated ligands
- discuss the importance of models in developing an understanding of the nature of ligands and chelated ligands, using specific examples
Students:
- use available evidence and process information from secondary sources to draw or model Lewis structures and analyse this information to indicate the bonding in selected complex ions involving the first transition series
- process information from secondary sources to give an example of the range of colours that can be obtained from one metal such as Cr in different ion complexes
