Question

In the following transition metals, the maximum number of oxidation states are exhibited by (A) chromium (Z = 24) (B) manganese (Z = 25) (C) iron (Z = 26) (D) titanium (Z = 22)

Tardigrade Admin · Accepted Answer

Manganese shows maximum number of oxidation states because it has

5

unpaired electrons in

3 d

and also contains

2

electrons in

4 s

sub-shell.

+ 2 + 3 + 4 + 5 + 6 + 7

Other metals show the following oxidation states

C r = + 2 + 3 + 4 + 5 + 6

F e = + 2 + 3

T i = + 2 + 3 + 4

Q. In the following transition metals, the maximum number of oxidation states are exhibited by

chromium (Z = 24)

manganese (Z = 25)

iron (Z = 26)

titanium (Z = 22)

Manganese shows maximum number of oxidation states because it has 5 unpaired electrons in 3d and also contains 2 electrons in 4s sub-shell. +2+3+4+5+6+7 Other metals show the following oxidation states Cr=+2+3+4+5+6 Fe=+2+3 Ti=+2+3+4

Manganese shows maximum number of oxidation states because it has $5$ unpaired electrons in $3 d$ and also contains $2$ electrons in $4 s$ sub-shell.
$+ 2 + 3 + 4 + 5 + 6 + 7$
Other metals show the following oxidation states
$C r = + 2 + 3 + 4 + 5 + 6$
$F e = + 2 + 3$
$T i = + 2 + 3 + 4$
