Based on Crystal Field Theory, discuss why [MnO4] is deeply coloured.
How would you account for the following?(i) Many of the transition elements are known to form interstitial compounds.(ii) The metallic radii of the third (5d) series of transition metals are virtually the same as those of the corresponding group members of the second (4d) series.(iii) Lanthanoids form primarily +3 ions, while the actinoids usually have higher oxidation states in their compounds, +4 or even +6 being typical.
Explain the following observations: (i) The enthalpies of atomisation of transition metals are quite high. (ii) There is a close similarity in physical and chemical properties of the 4d and 5d series of the transition elements, much more than expected on the basis of usual family relationship. (iii) The members in the actinoid series exhibit larger number of oxidation states than the corresponding members in the lanthanoid series.
