What is the coordination number of Cu metal in [Cu(NH3)4]S04?
Correct answer: B. 4
- A. 3
- B. 4
- C. 6
- D. 1
Explanation
The coordination number of an atom in a given molecule or a crystal refers to the total number of atoms, ion, or molecules bonded to the atom in question.The atoms, ions, or molecules that are bonded to the central atom (or molecule/ion) are called ligands.Since 4 NH3 molecules are bonded to Cu the coordination number of copper in [Cu(NH3)4]2+ is 4.

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.
