(1) Availability of 4f electrons results in the composition of compounds in +4 state for all the members of the series. (2) There is a gradual go down in the radii of the members with increasing nuclear number in the series. (3) altogether the members exhibit +3 oxidation state. (4) Because of similar properties the separation of autonomic nervous system: lanthanoids is not easy. autonomic nervous system: [1] 37. 32. In a facial expression centred cubelike lattice, atom A occupies the corner positions and atom B occupies the face centre positions. If whizz atom of B is lose from one of the face centred points, the formula of the compound is (1) A 2 B5 (3) AB2 autonomic nervous system: [1] 33.
