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

Multiple Choice Options

  • 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 4s and 3d electrons are used for bonding
  • D Once the d5 configuration is exceeded, the tendency to involve all the 3d electrons in bonding decreases.

Step-by-Step Verified Solution

Lower oxidation state of an element forms more basic oxide and hydroxide, while the higher oxidation state will form more acidic oxide/hydroxide. For example,
