transition element

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.

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

transi′tion el`ement

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.

tran·si·tion element

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.
