The species which donates electrons to the central metal atom in the coordination sphere is called _.
Correct answer: C. Ligand
- A. Anion
- B. Cation
- C. Ligand
- D. Acid
Explanation
A ligand is a specie that donates electrons to the central metal ion forming a dative covalent bond. Hence, the correct answer is C.A cation is a positively charged molecule and an anion is a negatively charged molecule. An acid is a specie that ionizes in an aqueous solution.

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.
