transition elements definition

The transition elements are metals. Definition of transition elements in the Definitions.net dictionary. transition elements or transition metals, in chemistry, group of elements characterized by the filling of an inner d electron orbital as atomic number increases. The transition elements are unique in that they can have an incomplete inner subshell allowing valence electrons in a shell other than the outer shell. This allows transition metals to form several different oxidation states. The visible light of a given energy level which is not absorbed produces a distinctly colored solution.
