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.
Iodine is not a compound. It is an element. Therefore, it has its own atoms: Iodine atoms.
The compound name of potassium and iodine is potassium iodide.
Iodine is a chemical element; not a mixture, not a compound.
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.
The compound ICI is commonly known as iodine chloride. It is a chemical compound made up of iodine and chlorine elements.

Iodine 2 Magnesium
The compound is named iodine pentafluoride, which is represented by the chemical formula IF5.
iodine pentabromide technically would be IBr5 but it doesn't exist. iodine monobromide's chemical formula is IBr though.
Magnesium and iodine is a element
