In context with the transition elements, which of the following statements is incorrect ?

Options

A. In addition to the normal oxidation states, zero oxidation state is also shown by elements in complexes.
B. In the highest oxidation states, transition elements show basic character and form cationic complexes
C. In the highest oxidation states of the first five transition elements (Sc to Mn). All the 4 s and 3d electrons are used for bonding
D. Once the `d^(5)` configuration is exceeded. The tendency to involve all the 3d electrons in bonding decreases.

Answer

B

Explanation

In the highest oxidation states, the transition metals cannot form cationic complexes. Also, they show acidic character because in the highest oxidation state. They can only accept the electrons but cannot lose them.
