The video tutorial explains how to write the Lewis structure for calcium nitride (Ca3N2), an ionic compound. It begins by identifying the valence electrons of calcium and nitrogen using the periodic table. Calcium, a metal, transfers electrons to nitrogen, a non-metal, to achieve stable octets. The video details the electron transfer process, resulting in ionic charges and the formation of ionic bonds. Finally, it illustrates the Lewis structure and explains the concept of a formula unit in the context of calcium nitride.
