Question

Write the formula to calculate spin only magnetic moment.

Answer 1

Hint: Magnetic moments are often used in conjunction with electronic spectra to gain information about the oxidation number and stereochemistry of the central metal ion in coordination complexes.

Complete answer:
Formula used: \[\mu = \sqrt {4s(s + 1)} \], \[\mu = \sqrt {n(n + 2)} \]
To calculate spin only magnetic moment,
\[\mu = \sqrt {4s(s + 1)} \] where s = Spin magnetic moment
\[\mu = \sqrt {n(n + 2)} \] where n = Number of unpaired electrons.

Note: In physics, mainly quantum mechanics and particle physics, a spin magnetic moment is the magnetic moment caused by the spin of elementary particles. In general, a magnetic moment can be defined in terms of an electric current and the area enclosed by the current loop.
An unpaired electron is an electron that occupies an orbital of an atom singly, rather than as part of an electron pair.
