Transition metal

An element that can form an atom or ion with a partially filled d-orbital.

1 of 10

Complex ion

Formed when pairs from a number of neutral molecules or ions (ligands) are donated by a coordinate covalent bond to a central metal ion

2 of 10

Ligand

An anion/molecule with a lone pair of electrons that forms a co-ordinate covalent bond with a central metal atom or ion in a complex.

3 of 10

co-ordinate bond

A shared pair of electrons between 2 atoms, one atom provides both electrons

4 of 10

Co-ordination number

The number of coordinate bonds to a central atom or ion in a complex

5 of 10

Ligand replacement

A reaction which involves substituting one ligand with another.

6 of 10

Monodentate ligand

A ligand which only uses 1 lone pair of electrons to form a co-ordinate bond with a central metal atom or ion in a complex

7 of 10

Bidentate ligand

A ligand which uses 2 pairs of electrons to form 2 coordinate bonds with a central metal atom or ion in a complex.

8 of 10

Polydentate ligand

A ligand which uses many lone pairs of electrons to form more than 2 coordinate bonds with a central atom or ion in a complex

9 of 10

Chelate

A complex containing polydentate ligands.
