| Question | Answer |
| Define a complex ion | A metal ion surrounded by coordinately bonded ligands |
| Define a ligand | A species containing a lone pair that can donate to form a coordinate bond with a metal ion |
| Define a coordinate bond | When both electrons in a bond come from one atom |
| Define coordination number | The number of coordinate bonds in a complex ion (not the number of ligands) |
| Define a bidentate ligand | A 'large' ligand which contains two lone pairs on different atoms that can both donate to form coordinate bonds |
| Define a ligand exchange reaction | When ligands are substituted in reaction (can be partial) |
