Trnsition elements show variable oxidati...

Trnsition elements show variable oxidation states. This is due to their valence electrons which are found in two different orbitals i.e., ns and (n-1) d. Up to (+II) oxidation state ns electrons are involved, but in higher oxidation states, electrons of (n-1) d sub-shells are also involved.
The transition metal which shows the highest oxidation state is

A

Mn

B

Pt

C

Fe

D

Ni.

Text Solution

Verified by Experts

The correct Answer is:
A
(a) The element Mn slows the highest oxidation state if +7 in its compounds.
