The video tutorial explains how to draw the Lewis structure for the hypo iodide ion (IO-). It begins by counting the valence electrons for iodine and oxygen, considering the additional electron due to the negative charge. The tutorial then demonstrates forming a chemical bond between iodine and oxygen and completing their octets. Finally, it shows how to represent the ion with brackets and a negative sign, offering an option to replace the electron pair with a single bond line.
