How do ligands bind to transition metal ions
WebJun 15, 2024 · We know that ligands make coordination bonds with d-orbitals of transition metals forming complexes. My question is, if that happened, all d-orbitals will be filled and … WebA ligand is a molecule that selectively binds to another molecule. Transition metals (transition elements) can form bonds called dative covalent bonds by accepting pairs of electrons (shown as :), from other ions or molecules. Both the shared electrons come from the same atom.
