The transition elements are those elements having a partially filled d or f subshell in any common oxidation state. The term "transition elements" most commonly refers to the d-block transition elements.

All the transition elements are metallic, but unlike the representative metals, they are likely to be hard, brittle, and have high melting points because of the relatively small size of their atoms and the existence of some covalent binding between ions.

Most elements can only use electrons from their outer orbital to bond with other elements. Transition metals can use the two outermost shells/orbitals to bond with other elements. It's a chemical trait that allows them to bond with many elements in a variety of shapes.

An up-to-date periodic table with detailed but easy to understand information ... The 38 elements in groups 3 through 12 of the periodic table are called "transition metals". As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat.
