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 `repectively hence

A

`x = y = z`

B

`x lt y lt z`

C

`x lt z lt y`

D

`z lt y lt x`

Text Solution

Verified by Experts

The correct Answer is:
C
`V = (Z = 23) rArr 3d^(3) 4s^(2) (n = 3)` (`n` is the number of unpaired electrons) `(x)`.
`Cr(Z=24) rArr 3d^(5) 4s^(1) (n = 6) (y)`
`Mn(Z = 25) rArr 3d^(5) 4s^(2) (n=5) (z)`
The more the number of unpaired electrons, the higher is the magnetic moment. So the answer is `x lt z lt y`.

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. Magnetic moments of Cr(Z=24),Mn^(o+)(Z=35) and Fe^(2+)(Z=36) are x,y and z respectively. Which of the following order is correct?

Magnetic moment of Cr(Z=24), Mn^+(Z=25) and Fe^(2+)(Z=26) are x,y,z. They are in order

Magnetic moment of Cr^(+2)(Z=24),Mn^(+2)(Z=25) and Fe^(2+) (Z=26) are x,y,z. they are in order

Among V(Z = 23), Cr(Z = 24), Mn(Z = 25) which will have highest magnetic moment.
