The order in which electrons are filled in atomic orbitals as per the Aufbau principle is illustrated below. As always, refer to the periodic table. However, this picture is at odds with the magnetic behavior of oxygen. In order to maximize the total spin, the electrons in the orbitals that only contain one electron all have the same spin (or the same values of the spin quantum number). She has taught science courses at the high school, college, and graduate levels. One way to remember this pattern, probably the easiest, is to refer to the periodic table and remember where each orbital block falls to logically deduce this pattern. It is also highly corrosive to metals and tissues. The noble gas preceding it is argon (Ar, Z=18), and knowing that vanadium has filled those orbitals before it, argon is used as the reference noble gas. It states that, in the ground state, the electrons occupy the atomic orbitals in their order of increasing energies, which is given by n+l rule. This gives the following: Note that in the orbital diagram, the two opposing spins of the electron can be visualized. If we look at the element after Nitrogen in the same period, Oxygen (Z = 8) its electron configuration is: 1s2 2s2 2p4 (for an atom).

As the p subshell is filled in the above example about the Aufbau principle (the trend from boron to neon), it reaches the group commonly known as the noble gases. Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence. Therefore, if the principal, azimuthal, and magnetic numbers are the same for two electrons, they must have opposite spins.
