Question

In which of the following processes spin only magnetic momentum does not change​

Answer 1

The spin only magnetic moment does not change​ in the following processes:

(b) N₂⁻ → N₂⁺

(c) Zn → Zn²⁺

(d) O₂ → O₂⁺

- CO has no unpaired electron and CO⁺ has one unpaired electron. So the spin magnetic moment gets changed.

- N₂⁻ and N₂⁺ both have all the paired electrons.

- Zn and Zn²⁺ both have all the paired electrons.

- O₂ and O₂⁺ both have unpaired electrons in them.

- So the spin only magnetic moment does not change​ for (b), (c) and (d).

Answer 2

Answer:

A spin magnetic moment id defined as the magnetic moment which is produced by the spin of elementary particles.

Explanation:

Spin-only magnetic moment can depend on two factors that include the number of unpaired electrons, n and the electron spin quantum number, S.

If there will be more number of unpaired electrons, more will be the Spin-only magnetic moment.

From the given processes spin-only magnetic moment of following processes will not change as the atoms involved in the processes have paired electrons and no unpaired electron.

B. N2- => N2+

C. Zn => Zn2+

D. O2 => O2-
