In chemistry, the term transition metal (or transition element) has three possible definitions: The IUPAC definition defines a transition metal as "an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete d sub-shell". IUPAC defines transition elements as an element having a d subshell that is partially filled with electrons, or an element that has the ability to form stable cations with an incompletely filled d orbital. 1 A Periodic Table with the d-block elements in darker red and the other transition metals, the lanthanides and actinides, in light red.
