उत्तर

 Enthalpy of Atomisatioun α number of volence electrons 
→ Greater the number of valence electrons. stronger is the resultant bonding.
→ For transition metals, more is (n -1) d electrons and n s electrons so more is intermetallic bonding. So, higher is enthalpy of Atomisation for Transmition metals.

Why do the transition elements have higher enthalpies of atomisation?


How would you account for the following : Transition metals form coloured compounds


In the series Sc (Z = 21) to Zn (Z = 30), the enthalpy of atomization of zinc is the lowest, i.e., 126 kJ mol−1. Why?


Describe the oxidising action of potassium dichromate and write the ionic equation for its reaction with iodide.


For M2+/M and M3+/M2+ systems, the E° values for some metals are as follows:

Cr2+/Cr −0.9 V
Mn2+/Mn −1.2 V
Fe2+/Fe −0.4 V
Cr3/Cr2+ −0.4 V
Mn3+/Mn2+ +1.5 V
Fe3+/Fe2+ +0.8 V

Use this data to comment upon:

  1. The stability of Fe3+ in acid solution as compared to that of Cr3+ or Mn3+ and
  2. the ease with which iron can be oxidised as compared to a similar process for either chromium or manganese metal.

How would you account for the following:

Cobalt (II) is stable in aqueous solutions, but in the presence of complexing reagents, it is easily oxidised.


Which of the following ions will exhibit colour in aqueous solution?


The disproportionation of \[\ce{MnO^{2-}_4}\] in acidic medium resulted in the formation of two manganese compounds A and B. If the oxidation state of Mn in B is smaller than that of A, then the spin-only magnetic moment (µ) value of B in BM is ______. (Nearest integer)


Account for the following:

Copper has an exceptionally positive `"E"_("M"^(2+)//"M")^0` value.


Compare the general characteristics of the first series of the transition metals with those of the second and third series metals in the respective vertical columns. Give special emphasis on the following point:
