Is there a difference between chelates and polydentate molecules?
If so how would you define each of them?

A chelate is a compound with a ligand bonded to a central atom at two or more points. This looks like a ring structure attached to the central atom.
A polydentate molecule has multiple ligands of this nature attached to the central atom.
So, a chelate can be monodentate, bidentate, tridentate, polydentate, etc. It's basically an umbrella term for the -dentates. Hope this helped!

I think once a polydentate ligand binds to a transition metal then it becomes a chelate.
