The correct definition of coordination number of a central metal atom in a complex is

Complex compounds are molecular compounds which retain their identities even when dissolved in water. They do not give all the simple ions in solution but instead furnish complex ions. The complex compounds are often called co-ordination compounds because certain groups called ligands are attached to the central metal ion by co-ordinate or dative bonds. Co-ordination compounds exhibit isomerism, both structural and stereoisomerism. The structure, magnetic property, colour and electrical properties of complexes are explained by various theories.
