... Firstly, the mathematical method. Squaring both sides of Equation 28.2 gives (5.95)2 = n(n + 2) Note that the square of the magnetic moment must be given to the nearest integer. This gives the quadratic equation 35 = n2 + 2n, which rearranges to n2 + 2n – 35 = 0 Factorising gives (n + 7)(n – 5) = 0 ...
