Question

If element 25X+Y has spin magnetic moment 1.732 B.M then

Options

A.number of unpaired electron = 1
B.number of unpaired electron = 2
C.Y = 4
D.Y = 6

Solution

= 1.732
Number of unpaired electrons, n = 1.
25X : [Ar] 4s23d5
For having one unpaired electron, 6 electrons are to be removed (2 from 4s & 4 from 3d).
∴      Y = 6.
