1.

which of the following graph is correct representation between atomic number (Z) and magnetic moment of d-block elements? [outer electronic configuration: (n-1)d^(x)ns^(1 or 2)]

Answer»




Solution :Magnetic moment=`SQRT(n(n+2))BM`
N:Number of unpaired `e^(-)`
As atomic number INCREASES in d-block element number of unpaired `e^(-)` FIRST increases upto MIDDLE then DECREASES.
