Any of the metallic elements within Groups 3 through 12 in the Periodic Table that have an incomplete inner electron shell and that serve as transitional links between the most and the least electropositive in a series of elements. They are characterized by multiple valences, colored compounds, and the ability to form stable complex ions. Also called transition metal.
(Elements & Compounds) chem any element belonging to one of three series of elements with atomic numbers between 21 and 30, 39 and 48, and 57 and 80. They have an incomplete penultimate electron shell and tend to exhibit more than one valency and to form complexes
any element in the four series of chemical elements with atomic numbers 21–29, 39–47, 57–79, and 89–107, that in a given inner orbital has less than a full quota of electrons. Also called transi′tion met`al.
Any of the metallic elements within Groups 3 through 12 in the Periodic Table. All the transition metals have two electrons in their outermost shell, and all but zinc, cadmium, and mercury have an incompletely filled inner electron orbital just beneath the outer orbital. Transition elements form alloys easily, have high melting points, and have more than one valence because of their incomplete inner shells. See Periodic Table. See Note at metal.

For instance, if the transition element is located in junction of a thick solid component connected to a moderately thick shell component, the transversal normal strains should be included in the finite element formulation.
As a result of the differences in rail geometries, a W-beam to Thriebeam transition element is typically used to connect and provide continuity between the two rail sections.
The potential problems of using the [epsilon]-NTU method in elemental heat exchanger models occur at the transition element (a tube or a segment) where both single-phase and two-phase refrigerants exist.
The concentrated stains produce a full spectrum of colors derived from earth elements in the metals and transition element group, and from ores, and refined chemicals.
3 also shows that a linear approximation (percentage change in [lambda] [approximately equals to] percentage change in transition element X elasticity) predicts larger changes in [lambda] quite accurately (see Heppell 1998, Caswell 2000), with the exception of one transition with a very high elasticity (61.1%; Fig.
As a consequence of the conservation of elasticity at a node, each loop has a "characteristic elasticity," which is defined as the elasticity of the transition element that is unique to that loop.
