Electron Configuration and Orbital Capacity

The video tutorial explains how to write the electron configuration for nitrogen. It begins by identifying the number of electrons using the atomic number from the periodic table. The tutorial then guides viewers through filling the 1s, 2s, and 2p orbitals, ensuring the total number of electrons matches nitrogen's atomic number. The final configuration is presented as 1s2 2s2 2p3.
