3.6k VIEWS. The element that usually does NOT show variable oxidation states is: Option 1) V. Option 2) Sc. Answers (1) A admin . Chromium has 3, Vanadium 4 and Manganese 5 common oxidation states. However, elements such as chlorine, bromine, and iodine also show +1, +3, +5 and +7 state. 300+ VIEWS. Zinc is a chemical element with the symbol Zn and atomic number 30. The element scandium (Z=21) does not exhibit variable oxidation state and yet it is regarded as a transition element. In case of halides, manganese doesn’t exhibit +7 oxidation state, however MnO 3 F is known.Cu +2 (aq) is known to be more stable than Cu + (aq) as the Δ hyd H of Cu +2 is more than Cu +, which compensates for the second ionisation enthalpy of Cu. Stability of oxidation states. 3:16 200+ LIKES. Clearly, the +2 oxidation state arises from the loss of … The transition element which does not show variable oxidation state is Sc. Iron, for example has two common oxidation states, +2 and +3. Higher oxidation states are shown by chromium, manganese and cobalt. Zinc is a slightly brittle metal at room temperature and has a blue-silvery appearance when oxidation is removed. Describe the variable oxidation state of 3d series elements. Text Solution. Oxidation State. 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). Zinc in the +1 oxidation state is $\text{[Ar]}3d^{10}4s^1$, and even in its highest, most common known oxidation state +2 (which the quoted values above seem to have forgotten) it's still $\text{[Ar]}3d^{10}$.No known zinc species in what we normally consider the realm of chemistry breaks that complete $3d^{10}$ subshell, and we would need a major revamp of our calculations and models … Post Answer. The oxidation state of an element is related to the number of electrons that an atom loses, gains, or appears to use when joining with another atom in compounds. All the elements of the halogen family exhibit -1 oxidation state. It also determines the ability of an atom to oxidize (to lose electrons) or to reduce (to gain electrons) other atoms or species. The element scandium (Z=21) does not exhibit variable oxidation state and yet it is regarded as a transition element. Answer: 1. Variable oxidation states may be understood rather better by a consideration of the electronic configurations of the states formed. Explain. ... (Z = 21) is a transition element but zinc (Z = 30) is not? Chromium has 3, Vanadium 4 and Manganese 5 common oxidation states. Note: It has been pointed out to me that there are a handful of obscure compounds of the elements sodium to caesium where the metal forms a negative ion - for example, Na-.That would give an oxidation state of -1. Option 3) Cu. You can ignore these if you are doing chemistry at A level or its equivalent. The transition element which does not show variable oxidation state is Sc. 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). Zinc does not exhibit variable valency due to 6.3k LIKES. 3.6k SHARES. The first transition metal Scandium exhibits only +3 oxidation state, but all other transition elements exhibit variable oxidation states by loosing electrons from (n-l)d orbital and ns orbital as … 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. Option 4) Ti. The element has the configuration [Ar]4s 2 3d 6. Oxidation states - Transition elements have a variety of oxidation states but the common oxidation state is +2 for 3d metals.
