Orbital filling diagram for nitrogen

The orbital filling diagram for nitrogen (atomic number 7) shows the distribution of its electrons in atomic orbitals. Nitrogen has a total of 7 electrons, which fill the orbitals in the following order: 1s² 2s² 2p³. This means the 1s orbital contains 2 electrons, the 2s orbital contains 2 electrons, and the 2p orbital contains 3 electrons, with the 2p electrons occupying separate orbitals according to Hund's rule to minimize electron repulsion. The resulting electron configuration reflects nitrogen's position in the Periodic Table and its chemical properties.
