• Transition elements have partially filled s orbitals.

• Transition elements have completely filled p orbitals.

What are coordination compounds and ligands?

• Coordination compounds are molecules that consist of a central metal ion or atom surrounded by ligands.

• Coordination compounds are molecules that consist of a central metal ion or atom surrounded by solvents.

• Ligands are molecules that consist of a central metal ion or atom surrounded by coordination compounds.

• Coordination compounds are molecules that consist of a central ligand surrounded by metal ions.

• Total charge of the complex

• Net charge of the complex

• Electric charge of the complex

Which property of transition elements allows them to form complex compounds?

• Coordination chemistry

• Ionic bonding

What is the coordination number of a complex?

• The coordination number of a complex is the number of protons attached to the central metal ion.

• The coordination number of a complex is the number of electrons attached to the central metal ion.

• The coordination number of a complex is the number of ligands attached to the central metal ion.

• The coordination number of a complex is the number of neutrons attached to the central metal ion.

What is the difference between a ligand and a complex ion?

• A ligand is a molecule or ion that donates electrons to form a coordinate bond, while a complex ion is a charged species consisting of a central metal ion bonded to ligands.

• A ligand is a molecule or ion that forms a coordinate bond with a central metal ion, while a complex ion is a charged species consisting of a central metal ion bonded to other ions.

• A ligand is a molecule or ion that accepts electrons to form a coordinate bond, while a complex ion is a charged species consisting of a central metal ion bonded to ligands.

• A ligand is a charged species consisting of a central metal ion bonded to other ions, while a complex ion is a molecule or ion that donates electrons to form a coordinate bond.

What is the role of ligands in coordination compounds?

• Ligands donate electrons to the central metal ion in coordination compounds.

• Ligands act as catalysts in coordination compounds.

• Ligands do not interact with the central metal ion in coordination compounds.

• Ligands accept electrons from the central metal ion in coordination compounds.

How does the charge on a ligand affect the stability of a complex?

• The charge on a ligand has no effect on the stability of a complex.

• The charge on a ligand increases the stability of a complex.

• The charge on a ligand decreases the stability of a complex.

• The charge on a ligand affects the stability of a complex by influencing the strength of the metal-ligand bond.
