Why do transition elements show variable oxidation states? How is the variability in oxidation state of transition metals different from these of p-block elements ? (i) In transition elements, the oxidation state differs by 1 e.g Cu + and Cu 2+.. Properties All transition metals except Sc are capable of bivalency. How is the variability in oxidation states of transition metals different from that of the p-block elements? Reason: Close similarity in energy of 4s and 3d electrons. In a d-d transition, an electron jumps from one d-orbital to another. And we get the trivalent Fe(III) state when one more 3d electron is removed, in addition to the two 4s electrons from the neutral Fe atom. A metal-to ligand charge transfer (MLCT) transition will be most likely when the metal is in a low oxidation state and the ligand is easily reduced. 1.Transition elements show variable state oxidation in their compounds because there is a very small energy difference in between (n-1)d and ns orbitals. Illustrate with examples. In p block elements the difference in oxidation state is 2 and in transition metals the difference is 1. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. In non-transition elements, the oxidation state differ by 2 e.g Pb +2 and Pb 4+ (ii) (a) d- block elements exhibit more oxidation states because of comparable energy gap between d and s subshell whereas f-block elements have large energy gap between f and d subshell. Ano The reason is the participation of (n-1)d ra4350280 is waiting for your help. Mn exhibits all the oxidation states from +2 to +7. Physics. The 4s electrons are first used and then 3d electrons. How is the variability in oxidation states of d-block different from that of the p-block elements? Answer: It is due to similar energy of (n – 1 )d and ns orbitals, electrons from both can be lost. (i) The variability of oxidation state of transition elements is due to incompletely filled d-orbitals as ns, and (n – 1) d electrons have very less energy difference. In case of transition elements, the variability in the oxidation state is due to participation of (n-1) d orbitals and ns orbitals. Add your answer and earn points. Transition metals are found in groups 3 through 12 on the periodic table, and each transition metal may have several oxidation states. d-d Transitions. As a result, electrons of (n-1)d orbitals as well as ns-orbitals take part in bond formation. In each case the metals (Cr and Mn) have oxidation states of +6 or higher. (ii) Scandium shows only +3 oxidation state. There is a great variety of oxidation states but patterns can be found. How is the variability in oxidation states of transition metals different from that of the non-transition metals ? How is the variability in oxidation state of transition metals different from these of p-block elements ?
