Ionic Bonds and Electron Transfer

The video explains the Lewis structure for magnesium nitride (Mg3N2), highlighting its ionic nature. Magnesium, a metal, transfers electrons to nitrogen, a non-metal, forming an ionic compound. The video details the electron transfer process, completing the octet for nitrogen and forming positive and negative ions. These ions attract each other, creating ionic bonds. The video concludes by discussing the crystal structure of solid magnesium nitride.
