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 ? Metal-metal bonding is more frequent in 4d or 5d series of transition metals than in the 3d series .

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.

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 bonding is more frequent in 4d or 5d series than in 3d series due to

Metal-Metal bonding is more frequent in 4d or 5d series than in 3d series due to

Metal-Metal bonding is more frequent in 4d or 5d series than in 3d series due to

Metal-metal bonding is more frequent in 4d or 5d series than in 3d series due to Tyndall effect. True/False

" The metallic radii of "4d" and "5d" series of transition metals are nearly the same.Why? "
