Q. Consider the following statements.
I. Transition elements show the great variety of oxidation states in their compounds.
II. The elements giving the greatest number of oxidation states occur at the extreme of the series.
III. The lesser number of oxidation states atoms have either too few electrons to lose or share or too many $d$-electrons for higher valence.
The correct statements are (choose the appropriate option)

The d-and f-Block Elements

Solution:

The elements which give the greatest number of oxidation states occur in or near the middle of the series. e.g. manganese exhibits all the oxidation states. Other statements are true.
