Show that the experimental data are consistent with a Lande g factor of 2 for each of the ions by calculating the saturation magnetic moment. Explain what this means for Cr. I've calculated J using Hunds rules and have the equation M = gμJn, where M is the saturation magnetic moment. BUT what do I use for n? i'm only given the number of electrons in a shell for each ion. Also would you think it wants me to determine g OR use a g value of 2 to determine M? any pointers REALLY appreciated on this, the exam is fast approaching. thanks.
