What is not true about transition metals?
Correct answer: C. They have only one valency
- A. They can make colored complexes
- B. They can be used as a catalyst
- C. They have only one valency
- D. They are d block elements
Explanation
Transition metals are known for their variable valencies. This means they can form ions with different charges due to the involvement of electrons from both their d and s orbitals.The other statements are true:Transition metals form colored complexes due to d-d transitions.Many transition metals act as catalysts because of their ability to change oxidation states.Transition metals are located in the d-block of the periodic table.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
