Chapter Name : The D- And F- Block Elements |

Topic Name : General Properties Of The Transition Elements |
|
Sub Topic Name : Oxidation States |
•
One of the notable features of a transition element is
the great variety of oxidation states it may show in its compounds.
•
The elements which give the greatest number of
oxidation states occur in or near the middle of the series. Ex: Manganese,
shows all the oxidation states from +2 to +7.
•
The lesser number of oxidation states at the extreme
ends stems from either too few electrons to lose or share (Sc, Ti) or too many
d electrons.
• At the other end, the
only oxidation state of zinc is +2
Periodic table, elements
Various precious metals such as silver, gold and
platinum and industrially important
