The spatial arrangement of the ligands attached to the central metal atom is called

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 coordination compounds because certain groups called ligands are attached to the central metal ion by coordinate or dative bonds. coordination compounds exhibit isomerism, both structural and stereoisomerism. the structure, magnetic property, colour and electrical properties of complexes are explained by various theories: Q. The oxidation number, coordination number and magnetic moment in the following complex is: [Cr(C_(2)O_(4))_(2)(NH_(3))_(2)^(-)]

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

The total number of electrons on the central atom including those gained by bonding is called the________ abbreviated as_______ .

The transtion metals form complexes that involve central metal atom coordinated with ligands. The geometry of these complexes depends upon the number of ligands associated with the central metal atom. Hexacoordinate metal complexes normally perfer to have octahedral geometry. From the following pair of oxides, indicate the number of d electrons of central metal atom. Also indicate which oxide will be coloriess and which will be colored. Explain your answer in brief.
