In context with the transition elements,...

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

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

In the highest oxidation states, transition elements 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 3d electrons are used for bonding

Once the `d^(5)` configuration is exceeded. The tendency to involve all the 3d electrons in bonding decreases.

Text Solution

Verified by Experts

The correct Answer is:

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.
