A) \[(n-2){{f}^{1-14}}(n-1){{s}^{2}}{{p}^{6}}{{d}^{0-1}}n{{s}^{2}}\]
B) \[(n-2){{f}^{10-14}}(n-1){{d}^{0-1}}n{{s}^{2}}\]
C) \[(n-2){{f}^{0-14}}(n-1){{d}^{10}}n{{s}^{2}}\]
D) \[(n-2){{d}^{0-1}}(n-1){{f}^{1-14}}n{{s}^{2}}\]
Correct Answer: A
Solution :
In lanthanides (At. no. of elements 58 to 71) the electronic configuration of three outermost shell is\[(n-2){{f}^{1-14}},\,\,(n-1){{s}^{2}}{{p}^{6}}{{d}^{0to1}},\,\,n{{s}^{2}}\].You need to login to perform this action.
