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

Options

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

Answer

A

Explanation

In the highest oxidation states, the transition metal shows acidic character.
