Solution - Explain Interstitial Compounds - General Properties of the Transition Elements (D-block)

Which of the d-block elements may not be regarded as the transition elements?

Give reasons: E° value for the Mn³⁺/Mn²⁺ couple is much more positive than that for Fe³⁺/Fe²⁺.

Which of the 3d series of the transition metals exhibits the largest number of oxidation states and why?

Explain giving reasons:  Transition metals and their many compounds act as good catalyst.

In what way is the electronic configuration of the transition elements different from that of the non-transition elements?
