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.

Metal-Metal bondin is more extensive in the 4d and 5d series of transition elements than the 3d series. Explain.

How would you account for the following? (i) Cr^(2+) is reducing in nature while with the same d-orbital configuration (d^14) Mn^(3+) is an oxidising agent. (ii) In a transition series of metals, the metal which exhibits the greatest number of oxidation states occurs in the middle of the series. (iii) Metal-metal bonding is more frequent for the 4d and the 5d series of transition metals than for the 3d series.

Assertion: The metals of 4d and 5d greater entalpies of atomisation than the corresponding elements of the 3d series. Reason: The metal-metal bond in 4d and 5d series are stronger than those in the 3d series.

Three occurs much more frequently metal-metal bonding in the compounds of heavy transition elements (3d series ). Assign reason.

Explain the following observation about the transition elements. (i) There is in general an increase in density of the element from titanium (Z=22) to copper (Z=29). (ii) There occurs much more frequent metal-metal bonding in compounds of heavy transition elements (3d series )

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.
