Sodium Ionic Charge and Electron Configuration

The video tutorial explains two main methods to determine the ionic charge of sodium: using periodic table trends and electron configuration. Sodium, found in Group 1 of the periodic table, typically has a 1+ ionic charge as it loses one electron to form a positive ion. The video also details sodium's electron configuration, showing how it has 11 electrons and loses one to achieve a stable configuration similar to neon. This process is further explained through sodium's bonding with elements like chlorine, where it loses its valence electron, resulting in a positive ionic charge.
