Question

1 Magnetic moments of V (Z=23), Cr (Z=24), and Mn (Z=25) are x,y, and z. hence
A) z<y<x
b)x=y=z
c)x<z<y
d)x<y<z​

Answer 1

Magnetic moment of V(Z = 23),Cr(Z = 24),and Mn(Z= 25) are x,y. Solution : V=(Z=23)⇒3d34s2(n=3) (n is the number of unpaired electrons) (x). The more the number of unpaired electrons, the higher is the magnetic moment.
