What does exactly polydentate mean? It has something to do with the amount of lone pairs a ligand shares, right? Can you also give examples of a monodentate, bidentate, and a tridentate? Thanks!

A polydentate is basically a ligand that can bind to the central atom at multiple sites (multiple atoms). An example of a monodentate would be H20 (the oxygen makes one bond with the central atom), a bidentate would be oxalate (the two oxygens that are not double bonded to the carbons can each form a bond to the central atom) and an example of a tridentate would be diethylenetriamine, NH(CH2CH2NH2)2 (the three nitrogens can each bond to the central atom).
