    				| 1. | Explain the position of actinoids in the periodic table. What is the action of sulphur on lanthanoids ? Calculate the magnetic moment of divalent ion in aqueous solution it its atomic number is 24. | 
| Answer» Position of actinoids in periodic table is third group and seventh period. Action of sulphur on lanthanoids `2Ln+3S rarr Ln_(2)S_(3)` Magnetic moment of divalent ion in aqueous solution. Z = 24, electronic configuration `=[Ar]3d^(5)4S^(1)` Divalent ion electronic configuration `=[Ar]3d^(4)` `therefore ` 4 unpaired electrons Magnetic moment `(mu)=sqrt(x(x+2))B.M.` `=sqrt(4(4+2))B.M.` `=4.89B.M.` | |
