Explain why:
(i) Transition elements form coloured compounds. (ii) `Cu^(+)` is diamagnetic but `Cu^(2+)` is paramagnetic (Z=29)

Explain why : Transition elements form alloys.

Explain why: Cu^(+) " is diamagnetic but " Cu^(2+) is paramag netic. (Z=29)

Explain why transition metals form complex compounds.

The tendency of the transition elements to form coloured compounds is attributed to

Explain why : Transition metals and their compounds act as catalyst.

Explain the following observation : (i) Transition elements generally form coloured compounds. (ii) Zinc is not regaded as a transition element.

Only transition elements are known to form carbonyls. Why?

Why are compounds of transition elements generally coloured ?

The colour of Cu^(o+) compounds is .

Assign reasons for each of the following : (i) Transiti9n metals generally form coloured compounds. (ii) Manganese exhibits the highest oxidation state of+ 7 among the 3d series of transition elements.
