WebA chelate is a type of ligand. A multidentate (dentate is Latin for tooth) ligand that uses more than one atom to bind to a metal in a coordination complex, see Figure 2.The metal is the electron-pair acceptor and the chelating agent the electron-pair donor. When binding to the metal ion, the chelate (ligand) forms a ring of atoms, of which the metal is one member. Web1 day ago · Chelate Compound Uses.
