1Define a complex ionA metal ion surrounded by coordinately bonded ligands
2Define a ligandA species containing a lone pair that can donate to form a coordinate bond with a metal ion
3Define a coordinate bondWhen both electrons in a bond come from one atom
4Define coordination numberThe number of coordinate bonds in a complex ion
(not the number of ligands)
5Define a bidentate ligandA 'large' ligand which contains two lone pairs on different atoms that can both donate to form coordinate bonds
6Define a ligand exchange reactionWhen ligands are substituted in reaction
(can be partial)
