:D. Okay, I did my research and I found the reason why 'Zinc is not considered to be a transition metal'. The transition metals are malleable (easily hammered into shape or bent). These metals tend to be very hard. Transition elements are defined as elements that form at least one ion that contains partially filled d orbitals. A Zn 2+ cation has shed the two electrons in … Hello, it's Gloria! The chemistry of zinc is almost entirely governed by its +2 ion charge. Start studying Transition Metals. Scandium is not a typical transition metal as its common Sc 3+ has no d electrons. Most transition metals are grayish or white (like iron or silver), but gold and copper have colors not seen in … This is because it has a relatively low melting and boiling point; in general transition metals have HIGH melting and boiling points, melting at 420 °C, and boiling at 900 °C, and has the lowest melting point of all the transition metals aside from mercury and cadmium. Transition metals look shiny and metallic. Hence zinc do not form colored aqueous ions because it do not have at least one vacant d-orbital in which it can receive an electron in a reaction. The elements of group 12 i.e., Zinc, Cadmium, and Mercury are generally not regarded as transition elements as their atoms and all ions formed have completely filled d-orbitals i.e., these do not have partially filled d-orbitals in atomic state or common oxidation state (Zn 2+, Cd 2+, Hg 2+). Zinc is not consider as a transition metal because its compounds or ions (Zn2+) contain a full filled d-orbital or sub shell and are unstable.Moreover it have only one ion which is the (Zn2+). The transition metals are compounds that form at least 1 stable ion where the compound has an incomplete d subshell. Explain why Zinc is not classified as a transition metal but is classified as a d block element. By definition, a transition metal must do this. Scandium and zinc are not transition metals simply because they do not form ions with incomplete d-subshells. The electronic configuration for a zinc atom is 1s 2, 2s 2, 2p 6, 3s 2, 3p 6, 4s 2, 3d 10. Therefore, Scandium is not a transition metal, because it forms only Sc3+ ions with n d-electrons, and Zn is not a transition metal because it forms only Zn2+ ions with all the 3d electrons present. Zinc has full d orbits and therefore does not meet the definition of a transition metal, which is "a metal that forms one or more stable ions with incomplete d orbits". 13.2.2 Explain why Sc and Zn are not considered to be transition elements. A transition metal element is defined as an element that possesses an incomplete d sub-level in one or more of its oxidation states. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Hence zinc do not form colored aqueous ions because it do not have at least one vacant d-orbital in which it can receive an electron in a reaction. Zinc is not consider as a transition metal because its compounds or ions (Zn2+) contain a full filled d-orbital or sub shell and are unstable.Moreover it have only one ion which is the (Zn2+). Zinc is generally not considered a transition metal as it has a full d-shell, though it is considered a transition metal in some texts. Sc forms 3+ ions, losing the two 4s electrons and a 3d electron (1s2, 2s2, 2p6, 3s2, 3p6) Zn forms 2+ ions, losing only the two 4s electrons (1s2, 2s2, 2p6, 3s2, 3p6, 3d10)
