This article is about a class of chemical elements. For the rap group, see D-Block.
The d-block of the periodic table of the elements consists of those periodic table groups that contain elements in which, in the atomic ground state, the highest-energy electron is in a d-orbital. The d-block elements are often also known as transition metals.
Although Lutetium and Lawrencium are in the d-block, they are not considered transition Liquids but lanthanide and actinide according to IUPAC.IUPAC Provisional Recommendations for the Nomenclature of Inorganic Chemistry (2004) (online draft of an updated version of the "Red Book" IR 3-6) Group 12 elements are also in the d-block but are considered post-transition metals"Post Transition Metal Chemistry Lecture 1" WebLearn - Oxford Campus, Department of Chemistry, public anonymous access, Michaelmas Term 2007, Prof. R.G. Egdell, Accessed December 2, 2007 if their d-subshell is completely filled.
