The above orbital diagram shows the electronic configuration of nitrogen. An orbital diagram is a way of representing the arrangement of electrons in an atom using boxes to represent orbitals and arrows to represent electrons. In this diagram, there are two boxes representing the first energy level (closest to the nucleus) and three boxes representing the second energy level. The boxes are labeled with the appropriate sublevel (s, p, d, or f) and the number of electrons in each sublevel is shown with arrows pointing up or down. Nitrogen has seven electrons, which are distributed among the sublevels according to the aufbau principle and Hund's rule. The first two electrons occupy the 1s sublevel, while the remaining five electrons occupy the 2s and 2p sublevels. The 2s sublevel can hold up to two electrons, which are shown in the first box of the second energy level. The 2p sublevel can hold up to six electrons, but in this case, only three of the four available boxes are filled with one electron each, leaving one box empty. Overall, the electronic configuration of nitrogen is 1s2 2s2 2p3, meaning it has two electrons in the 1s sublevel, two electrons in the 2s sublevel, and three electrons in the 2p sublevel.
