Question

Curie paramagnetism: One often compares not the measured and calculated Curie constants but rather the so-called effective magneton number p with p2 = g2 JJ(J+1). Calculate p for the following ions and compare your result to the experimental value given in brackets: Nd3+ with three 4f electrons (3.5), Gd3+ with seven 4f electrons (8.0), Cr2+ with four 3d electrons (4.9), and Fe2+ with six 3d electrons (5.4)
