Zinc isn’t a transition metal as it contains a full d sub level in all of its oxidation states. The elements of the first transition series. In higher oxidation states, the bonds formed are essentially covalent. Common oxidation state of Scandium, a transition element is /are (At. In transition elements, there are greater horizontal similarities in the properties in contrast to the main group elements because of similar ns 2 common configuration of the outermost shell. Scandium is one of the two elements in the first transition metal period which has only one oxidation state (zinc is the other, with an oxidation state of +2).. Chromium has 3, Vanadium 4 and Manganese 5 common oxidation states.. compounds Scandium dihydride: ScH2 Scandium trihydride: ScH3 Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. You can study other questions, MCQs, videos and tests for NEET on EduRev and even discuss your questions like Scandium is an element which chemists usually ignore! The element is most commonly used in aerospace industry. EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something. Oxidation State: 3 Crystal Structure: hexagonal. Scandium is more common in the sun and certain stars than on Earth. In the image above, the blue-boxed area is the d block, or also known as transition metals. An examination of common oxidation states reveals that excepts scandium, the most common oxidation state of first row transition elements is +2 which arises from the loss of two 4s electrons. It is also regarded as a rare earth element because its chemical properties are similar to the rare earths, and it is found in the same ores. Scandium is not a typical transition metal as its common Sc 3+ has no d electrons. Wikipedia reports a double chloride $\ce{CsScCl3}$ where scandium is clearly in the oxidation state +2.. For example: manganese shows all the oxidation states from +2 to +7 in its compounds. Although the transition metals have many general chemical similarities, each one has a detailed chemistry of its own. Answers of Common oxidation state of scandium, a transition element, is/are [Ar.No.of Sc = 21]a)+4b)+1c)+2 and +3d)+4 and +1Correct answer is option 'C'. 2. Scandium, however, is limited to the plus three oxidation state, meaning its chemistry is not quite as diverse as some of its transition metal counterparts. A transition metal element is defined as an element that possesses an incomplete d sub-level in one or more of its oxidation states. Of the familiar metals from the main groups of the Periodic Table, only lead and tin show variable oxidation state to any extent. Scandium is more common in the sun and certain stars than on Earth. Scandium is a transition metal. For example, the oxidation state of Iron is between 2+ to 6+. No =21) The most common oxidation state of scandium in is +3. It is predicted that even a +10 oxidation state may be achievable by platinum in the tetroxoplatinum(X) cation (PtO 2+ 4). Hence,it is regarded as a transitio elements. Iron. Common oxidation state of scandium, a transition element, is/are [Ar.No.of Sc = 21]. Scandium in the ground state has one electron in the 3d-subshell. This discussion on Common oxidation state of scandium, a transition element, is/are [Ar.No.of Sc = 21]a)+4b)+1c)+2 and +3d)+4 and +1Correct answer is option 'C'. Can you explain this answer? Similarly, the elements from second and third transition series gain more stability in higher oxidation state than the ones from the first series. A silvery-white metallic d-block element, it has historically been classified as a rare-earth element, together with yttrium and the lanthanides.It was discovered in 1879 by spectral analysis of … The transition element which does not show variable oxidation state is Sc. Their behavior as an acid or base is dependent on the oxidation states of the oxide. Answered By Hence, it is considered as a transition element. The blue color of the aquamarine variety of beryl is thought to be caused by scandium impurities in it. For the elements of first transition series +2 oxidation state is the most common oxidation sate (except for scandium). All three metals react with excess oxygen, however, to produce the corresponding oxides in the +5 oxidation state (M 2 O 5 ), in which polarization of the oxide ions by the high-oxidation-state metal is so extensive that the compounds are primarily covalent in character. Its compound mostly exists in +3 oxidation state. Question bank for NEET. Not all the d-block elements are transition metals. A rare transition element, scandium was discovered in 1878 by L. Nilson in Scandinavia. Can you explain this answer? Copper is an ideal example of a transition metal with its variable oxidation states Cu2+ and Cu3+. All the other elements have at least two different oxidation states. The following figure shows the d-block elements in periodic table. Correct answer is option 'C'. Can you explain this answer? Oxidation states, (aka oxidation numbers), are numbers that show how many electrons the element would lose or gain if it were to bond to other atoms.
