Web8 Aug 2024 · To determine whether the elements are paramagnetic or diamagnetic, write out the electron configuration for each element. He: 1s 2 subshell is filled. Be: 1s 2 2s 2 subshell is filled. Li: 1s 2 2s 1 subshell is not filled. N: 1s 2 2s 2 2p 3 subshell is not filled. WebXN i=1 s i, (3) then the model is ferromagnetic if and only if S 6= 0. At 0K, S is either +N or −N. In the opposite limit, that of T → ∞ then the interactions are irrelevant. Then adjacent spins are as likely to be antiparallel as parallel and so are as likely to point up as down. So half the spins will point up and half down. Therefore ...
