Question

magnetic momentum of Sc+1
​

Answer 1

Answer:

The spin magnetic moment is calculated by given below formula : where n is number of unpaired electron. So, number of unpaired electron in Sc+3 is....

Magnetic moment is calculated by the formula

μ = √n(n+2) B.M

find the no. of unpaired electrons.

Atomic no. Of Sc is 21.

So, the electron configuration will be

[Ar] 4s^2 3d^1

Since it’s given Sc^+1

One electron will be removed from the outermost orbit as

[Ar] 4s^1 3d^1

Here we can see,

There are 2 unpaired electrons.

So,

μ = √2(2+2)

μ = √8 B.M

Answer 2

Magnetic moment is calculated by the formula

μ = √n(n+2) B.M

Where,
μ is the Magnetic Moment.
n is the no. of unpaired electrons.
B.M. = Bohr Magneton ( unit of magnetic moment)

First find the no. of unpaired electrons.

Atomic no. Of Sc is 21.

So, the electron configuration will be

[Ar] 4s^2 3d^1

Since it’s given Sc^+1
One electron will be removed from the outermost orbit as

[Ar] 4s^1 3d^1

Here we can see,
There are 2 unpaired electrons.
So,
μ = √2(2+2)

μ = √8 B.M
