The Transition Metals
The transition metals have a set of properties which are characteristic of them.

Partially filled d sub-shell
- The transition metals are not just the metals in the d-block. The final triad of the d-block (Zn, Cd, Hg) are not usually thought of as transition metals.
- This is because they have a full d sub-shell.
- The transition metals share their properties, and these properties come about because of a partially filled d sub-shell.

Metallic properties
- The transition metals are metals. This means they have the usual metal properties:
- Hard.
- Sonorous (ring when hit).
- Shiny.
- Good electrical conductors.
- Good thermal conductors.

Ionic properties
- The ions of the transition metals have properties which are NOT shared by other metals:
- They have multiple oxidation states.
- They form coloured ions in solution.
- They are often great catalysts for chemical reactions.
- They form complexes with ligands (we’ll explain next what that means).

Ligands
- A ligand is a molecule which forms a dative bond with a transition metal.
- The ligand donates a lone pair to the transition metal ion.
- An ion with ligands attached to it is called a complex ion.
- We define the co-ordination number of an ion as the number of dative bonds between a metal ion and its ligands.
