Formula: I2
Iodine, like all the other halogens, normally has divalent molecules: therefore, the formula for crystalline iodine is I2.
Formula: I2
The chemical formula for potassium iodine is KI
Iodine is a chemical element; not a mixture, not a compound.
if u heated them then its a physical change if u chucked another chemical on them its a chemical change if u did both then its a change of clothes
Iodine crystals are very poor conductors of heat and electricity
You think probably to sublimation of iodine.

Iodine is a chemical element; not a mixture, not a compound.
It is a physical change (sublimation).
Solid iodine can be found as pure crystals.
Iodine crystal is solid Iodine. Iodine solution is when Iodine crystals are dissolved in water.
In order for something to be considered a change some sort of change must occur. A crystal is an object, not a type of change. Dark violet iodine crystals are pieces of relatively pure elemental iodine.

I bought iodine crystal from china, very fast delivery and perfet quality. supplier email: info@pharmacychem.com
It is a change of state and therefore a physical change.
