Re: Ligand polydentate
I'm not entirely sure, but I think it depends on the lone pairs within a molecule. Like water is a monodentate because it can only bond through oxygen which has 2 sets of lone pairs. With en (ethylenediamine) since it has multiple nitrogens with lone pairs, it is able to bond through multiple site, making it a polydentate.

Re: Ligand polydentate
It depends on how many lone pairs the ligand has. For example, en has two nitrogen with lone pairs and is a bidentate.

So only one of the lone pairs on oxygen is used ?

Yes, only one oxygen is used. This is shown in the naming compound sheet linked in another post indicating the water molecule is OHO with the bond to the first oxygen
