For questions about the characteristic physical properties, chemical reactions, etc. of d-block elements, group 3-12, or their compounds. Do not use this tag if your questions is about general properties of metals, use [metal] instead. Also see [rare-earth-elements].
From the IUPAC Red Book 2005, IR-3.5:
For example, the elements of groups 3–12 are the d-block elements. These elements are also commonly referred to as the transition elements, though the elements of group 12 are not always included; [...]
These metals, like all metals, are ductile and have the capability to conduct electricity as well as heat.
