NOTE-Some Principal Energy Levels start to fill before previous ones finish. ex 4s fills before 3d, because 4s has less energy than 3d. It must fill first.
WebSep 12, 2024 · This model ignores the interactions between the electrons but respects the exclusion principle. For the special case of \(T = 0 \, K\), \(N\) electrons fill up the energy levels, from lowest to highest, two at a time (spin up and spin down), until the highest energy level is filled. The highest energy filled is called the Fermi energy.
