Long Answer Type
Short Answer TypeIn what way are the observed oxidation states of the lanthanides related to their electronic configurations?
Long Answer TypeDescribe 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.
Short Answer TypeWhy are transition metals able to form alloys?
An alloy is a blend of metals prepared by mixing the components. Alloys may be homogeneous solid solutions in which the atoms of one metal are distributed randomly among the atoms of the other. Such alloys are formed by atoms with metallic radii that are within about 15 percent of each other. Because of similar radii and other characteristics
of transition metals, alloys are readily formed by these metals.
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.
