Metal-metal bonding is more frequent in 4d or 5d series than in 3d-ser

1.	Metal-metal bonding is more frequent in 4d or 5d series than in 3d-serie. This is because of :– (a) Their greater enthalpy of atomization (b) the large size of the orbitals which participates in the metal-metal bond formation (c) their ability to involve ns and (n–1) d-electrons in the bond formation (d) the comparable size of 4d and 5d-series elements
Answer» Correct option (a) Their greater enthalpy of atomization
