The video tutorial explains how to draw the Lewis structure for the I2+ ion, also known as iodine dichloride cation. It begins by counting the valence electrons and placing iodine as the central atom with two chlorine atoms on either side. The video details the process of completing the octet for each atom and checking formal charges to ensure the structure is correct. It then discusses the molecular geometry, describing it as bent due to the presence of lone pairs, and uses AXE notation to confirm the geometry.
