The magnetic properties of atoms

Similarly, if the angular momentum of an electron in an atom has a nonzero value, there is a flow of current about an axis and the system possesses a magnetic moment. The magnetic moment of the atom is the resultant of the moments due to the spin angular momentum and the orbital angular momentum of all the electrons in the atom. 

If a current I flows in a loop of wire, the loop has a magnetic moment given by 

Now if we imagine an electron moving with a velocity y in an orbit of radius r, the number of times the electron passes any point in the orbit in one second is the velocity divided by the circumference of the orbit, v/lnr. If we multiply this by the charge on the electron, — e, we obtain the charge passing that point in one second, which is the current, /. 

The angular momentum, = mrr, ifthe orbit lies in the xy-plane. Since t = MJmr, 

This formula from classical physics is correct for the electron only for the orbital angular momentum. The negative sign simply means that the magnetic moment is opposite in direction to the angular momentum vector. For spin, it turns out that the value of y is about twice as large (2.00232 times to be exact) as that in Eq. 24.39. Consequently, the magnetic moment of the electron is usually expressed as

I hope and believe that the present statements will prove useful in the elucidation of the magnetic properties of atoms and molecules, and further for explaining the flow of electricity in solid bodies. 

We saw in Table 1.1 the eigenfunctions for a p orbital, for which the permitted m values are 1, 0, and — 1, and Figure 1.6 shows their orientation in space. The case of d orbitals is shown in Figure 1.7. The magnetic properties of atoms are related to the magnetic quantum number. 

Experimental support for the conclusions reached on the basis of Hund s rule (e.g., for the configuration shown in Figure 1.9 for carbon) is provided from spectroscopic measurements of the magnetic properties of atoms. The magnetism of an atom is...

Why do we care about the term symbols First, it tells us about the magnetic properties of atoms due to unpaired spins. In addition, you will need to know the term symbols in upper level courses in inorganic chemistry because the overall value of the P gives spatial...
