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

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

Solution & Step-by-step Explanation

In their highest oxidation states, transition metals tend to be more covalent and acidic rather than basic. For example, MnO_{4}^{-} and Cr_{2} O_{7}^{2 -} are anionic complexes where the metal is in a high oxidation state and the character is acidic.

Try it yourself before checking the explanation above.

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

In addition to the normal oxidation states, the zero oxidation state is also shown by these elements in complexes.

In the highest oxidation states, the transition metal show basic character and form cationic complexes.

In the highest oxidation states of the first five transition elements (Sc to Mn), all the 4 s and 3 d electrons are used for bonding.

Once the d^{5} configuration is exceeded, the tendency to involve all the 3 d electrons in bonding decreases.
