What's the importance of a chelate and are they stronger than normal coordination compounds?

A chelate is a multi dentate ligand, meaning it is a complex containing a ligand that forms a ring of atoms the include the central metal atom. Therefore chelating ligands can bind cations tightly. They are stronger than coordinate compounds.

A chelate is a made up of many complex compounds where there is a central metal atom that binds to other ligands in a ring/cyclical type structure. I believe the ligand is also polydentrate.

Also chelates can only form when the other atom in the initial ring is adjacent, so in a carbon ring the two ligands attached to the carbon ring must be the carbons next to each other or else there would be too much space and the extra ring won't form.

Just to clarify, then is it only called a chelate if it has an extra ring?
