What is a coordination complex?

• A compound where molecules are coordinated in a straight line.

• A compound that combines with water to form a hydrate.

• A compound consisting of a central metal atom or ion bonded to one or more ligands.

• A compound formed by the sharing of electrons between metal atoms.

Which property of transition metals allows them to act as catalysts?

• High melting point

• Ability to adopt multiple oxidation states

• Low reactivity

• High density

Why do compounds of transition metals often appear colored?

• Because they absorb all wavelengths of light.

• Because they reflect all wavelengths of light.

• Because they absorb certain wavelengths of light, which results in the complementary color being observed.

• Because they have high melting points.

• +1

• +2

• +3

• +4
