Electron Configuration of Fluorine

The video tutorial explains how to find the electron configuration for fluorine. It begins by identifying the atomic number of fluorine on the periodic table, which indicates the number of electrons. Using a chart, the tutorial guides viewers through the process of filling the 1s, 2s, and 2p orbitals with electrons, resulting in the configuration 1s2 2s2 2p5. The video concludes with a summary of the configuration process.
