Magnetic moment of V(Z = 23),Cr(Z = 24)...

Magnetic moment of `V(Z = 23),Cr(Z = 24),and Mn(Z= 25)` are ` x,y,z` respectively hence

A

`z lt y lt x`

B

`x = y = z`

C

`x lt z lt y`

D

`x lt y lt z`

Text Solution

Verified by Experts

The correct Answer is:
C
( c) Magnetic moments `sqrt(n(n + 2)) B.M` where `n` is the number of unpaired electron.
`V(Z = 23) (Ar) 3 d^3 4 s^2 n = 3, sqrt15 BM = x`
`Cr(Z = 24) (Ar) 3 d^5 4 s n = 6, sqrt48 BM = y`
`Mn (Z = 25) (Ar) 3 d^5 4 s^2 n = 5, sqrt35 BM = z`.

Magnetic moment of V(Z = 23),Cr(Z = 24),and Mn(Z= 25) are x,y,z repectively hence

Magnetic moments of V(Z = 23), Cr(Z = 24), Mn (Z = 25) are x,y,z. HencE:

Transition metals and many of their compounds show paramagnetic behaviour where there are unpaired electron or electrons. The magnetic moment arises from the spin and orbital motions in ions or molecule. Magnetic moment of n unpaired electrons is given as mu=sqrt(n(n+2)) Bohr magneton Magnetic moment increases as the number of unpaired electrons increases. Q.
