The number of lone pair of electrons provided by the ligands to the central transition metal atom or ion is called:
Correct answer: B. Coordination number
- A. Oxidation number
- B. Coordination number
- C. Effective atomic number
- D. Coordination complex
Explanation
The number of lone pair of electrons provided by the ligands to the central metal atom or ion is called the coordination number of the central metal atom or ion. Thus, optioon B is correct.

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.
