D-block

It has been suggested that this article or section be merged into Transition metal. (Discuss)

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 metals but lanthanide and actinide according to IUPAC.^[1] Group 12 elements are also in the d-block but are considered post-transition metals^[2] if their d-subshell is completely filled.^[1]
