Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose coil. This makes a linear triiodide ion complex with is soluble. The triiodide ion ion slips into the coil of the starch causing an intense blue-black color.
Iodine added to a solution or directly on a potato or other materials such as bread, crackers, or flour will produce a blue-black color results if starch is present. If starch amylose is not present, then the color will stay orange or yellow.
The compound made of silver and iodine is silver iodide(AgI). Because this is a compound with a metal (silver) and a non-metal (iodine), we use the metal's name with the non-metal's name changed to end in -ide.
Iodine is not a compound. It is an element. Therefore, it has its own atoms: Iodine atoms.
