Violet color of [Ti(H2O)4]+is due to:
Correct answer: A. Central metal ion
- A. Central metal ion
- B. Water molecule
- C. Complex ion
- D. Outer anion
Explanation
The central metal ion has the coordination number 4. To bring the electrons from lower to higher energy levels, the photon is absorbed and the colour seen is complementary to the wavelength absorbed.

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.
