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

Chemistry · NEET · NTA Exams — d- and f- Block Elements

1. In addition to the normal oxidation state, the zero oxidation state is also shown by these elements in complexes.
2. In the highest oxidation states, the transition metal shows basic character and form cationic complexes.
3. In the highest oxidation states of the first five transition elements (Sc to Mn), all the 4s and 3d electrons are used for bonding.
4. Once the d⁵ configuration is exceeded, the tendency to involve all the 3d electrons in bonding decreases.

Answer

(B) In the highest oxidation states, the transition metal shows basic character and form cationic complexes.
