The actual "chemical formula does not, however this should help:-
Iodine is a bluish-black, lustrous solid, volatilizing at ordinary temperatures into a blue-violet gas with an irritating odor.
It forms compounds with many elements, but is less active than the other halogens, which displace it from iodides. Iodine exhibits some metallic-like properties.
It dissolves readily in chloroform, carbon tetrachloride, or carbon disulpfide to form beautiful purple solutions. It is only slightly soluble in water.
Iodine compounds are important in organic chemistry and very useful in medicine. Forty-two isotopes and isomers are recognized. Only one stable isotope, 127I, is found in nature.
The artificial radioisotope 131I, with a half-life of 8 days, has been used in treating the thyroid gland. The most common compounds are the iodides of sodium and potassium (KI) and the iodates (KIO3). Lack of iodine is the cause of goiter. Iodides and thyroxin, which contains iodine, are used internally in medicine, and a solution of KI and iodine in alcohol is used for external wounds. The deep blue color with starch solution is characteristic of the free element.
iodine is the only halogen in solid form. so it is the halogen which gives violet vapours on sublimation...
Iodine is a nonmetal element that can sublime, meaning it can change directly from a solid to a gas without passing through a liquid phase.
One example of an element that sublimes on heating is iodine. When solid iodine is heated, it directly changes into a gas without passing through a liquid phase.
One way to separate iodine from zinc oxide is through sublimation. Since iodine sublimes at a lower temperature than zinc oxide, you can heat the mixture to a temperature where iodine sublimes, and then collect the iodine vapors while leaving behind the zinc oxide.
Some solids are Carbon dioxide, Snow, Iodine and Naphthalene
Sublimation of iodine to iodine vapor is a physical change. It is a phase transition in which a substance goes directly from a solid to a gas without changing its chemical composition.

Iodine is a brittle solid at room temperature and does not exhibit ductility. It easily sublimes into a gas when heated.
Iodine is an element that sublimes when gently heated. Sublimation is the process of a substance transitioning directly from a solid to a gas phase without passing through the liquid phase.
Iodine sublimes into a purple gas without passing through a liquid phase. This is a change in physical state, which is a physical change.
If zinc chloride is heated strongly the solid will sublime.
When iodine is heated, it sublimes directly from a solid to a purple gas. The gas produced is diatomic iodine molecules (I2).
Iodine ------------------------------------------- The element you describe sounds like iodine, a good test to make sure that it is iodine is to see if the substance sublimes. This means a solid sample of iodine will turn straight from a solid into a gas with no liquid stage.
