Explain giving a suitable reason for each of the following : (i) Transition metals and their compounds are generally found to be good catalysts. (ii) Metal-metals bonding is more frequent for the 4d and the 5d series of transitions metals than that for the 3d series.

Explain the following observations about the transition/ inner-transition elements : (i) There is in general an increase in density of elements from titanium (Z=22) to copper (Z=29). (ii) There occurs much more frequent metal-metal bonding in compounds of heavy transition elements (3rd series). (iii) The members in the actinoid series exhibit a large number of oxidation states than the corresponding members in the lanthanoid sereis

(a) Complete the following chemical reaction equations : (i) MnO_(4(aq))^(-) + C_(2)O_(4(aq))^(2-) + H_((aq))^(+) to (ii) Cr_(2) O_(7 (aq))^(2-) + Fe_((aq))^(2+) + H_((aq))^(+) to (b) Explain the following observations about the transition/inner transition elements : (i) There is in general an increase in density of element from titanium (Z = 22) to copper ( Z= 29). (ii) There occurs much more frequent metal-metal bonding in compounds of heavy transition elements ( 3^(rd) series). (iii) The members in the actinoid series exhibit a larger number of oxidation states than the corresponding members in the lanthanoid series.

Incorrect statement for radius of 3d series metal/ions:

State the reason for the following : (i) Cu (I) ion is not stable in an aqueous solution. (ii) Unlike Cr^(3+),Mn^(2+),Fe^(3+) and the subsequent other M^(2+) ions of the 3d series, the 4d and 5d series metals generally do not form stable oxidation states.

Among 3d transition series the IE

Why is enthalpy of atomisation is the lowest for Zn in 3d series of transition elements ?

First IE of 5d seties element are higher than those of 3d and 4d series elements. This is due to:

Assertion : The order of atomic radii of Cu, Ag and Au is Cu lt Ag ~~ Au . Reason : The atomic radii of 4d series elements are larger than those of 3d series elements but generally the radii of 4d and 5d series elements are almost identical.

How would you account for the following : (i) The metallic radii of the third (5d) series of transition metals are virtually the same as those of the corresponding group members of the seconds (4d) series. (ii) There is a greater range of oxidation states among the actinoids than among the lanthanoids.
