WebA chelate is a molecule that consists of a central metal atom that is linked to a ligand that has at least two or more donor sites. The creation of a cyclic configuration around the core metal atom is caused by di- and polydentate ligands. Such a cyclic metal complex is known as a chelate, and the ligands that produce chelates are known as ... WebA molecule that directly gets bonded with the central atom is termed as a ligand. If the molecule bonds two pairs of electrons to the center of an atom, it is known as a bidentate ligand. The bidentate is a Lewis base that gives away two pairs of different electrons. Such ligands attached to the central atoms are termed as chelating ligands.
