Why do transition elements show color?
Correct answer: C. Due to d orbitals
- A. Due to both s and d orbitals
- B. Due to s orbitals
- C. Due to d orbitals
- D. Due to unpaired electrons
Explanation
Transition elements have incomplete d orbitals, which allow electrons in other orbitals like s orbitals to get excited and jump into these incomplete d orbitals, creating an energy difference corresponding to the wavelength of certain colors from the visible spectrum.

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.
