d -block elements are called
Correct answer: C. Transition metals
- A. Coinage metals
- B. Noble metals
- C. Transition metals
- D. Alkali metals
Explanation
Transition metals are a group of chemical elements that have a partially filled d subshell. This gives them a variety of properties that are different from the other groups of metals. Transition metals are often more reactive than the s-block metals and have higher melting points than the p-block metals. They are also often used in catalysts and other applications where their properties are needed.

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
