How is the variability in the oxidation states of transition metals different from that of the nontransition metals? Illustrate with examples.
Assign reasons for the following:
The enthalpies of atomisation of transition metals are high.
Describe the general characteristics of the transition elements with special reference to their tendency to:
(i) Exhibit paramagnetism.
(ii) Form complex compounds.
(iii) Their catalytic behaviour.
In what way are the observed oxidation states of the lanthanides related to their electronic configurations?
