The d-and f-Block Elements
Report Error
A
In addition to the normal oxidation states, the zero oxidation state is also shown by these elements in complexes.
11%
B
In the highest oxidation states, the transition metals show basic character and form cationic complexes.
74%
C
In the highest oxidation states of the first five transition elements (
S
c
to
M
n
), all the
4
s
and
3
d
electrons are used for bonding.
5%
D
Once the
d
5
configuration is exceeded, the tendency to involve all the
3
d
electrons in bonding decreases.
11%
Solution:
When the transition metals are in their highest oxidation state, they no longer have tendency to give away electrons, thus they are not basic but show acidic character and form anionic complexes.
