The central metal atom along with ligand is called:
Correct answer: B. Coordination sphere
- A. Coordination number
- B. Coordination sphere
- C. Chelates
- D. None of these
Explanation
Option b is the correct answer. It refers to the central metal atom/ion along with its attached ligands in a coordination complex. The coordination sphere includes the central metal atom/ion and all of the ligands directly bonded to it. So, it encompasses both the metal and the ligands, making it the most appropriate option.

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.
