As with all matter, it can be any of these phases depending on temperature and pressure. At STP it is a black solid. Keeping the pressure constant but slowly raising the temperature it sublimes (i.e. transitions directly from solid to gas without becoming liquid) to a violet colored gas.
The triple point (the temperature and pressure at which a material is simultaneously solid, liquid, and gas) of iodine is 386.65 K, 12.1 kPa or 236.30 F, 1.755 psi.
A "vapor" in chemistry is always the gas phase of a substance that is more familiar in one of its condensed phases: liquid or solid. Therefore, iodine vapor is the gas phase of the element iodine, and has the same molecular composition as the solid, I2. Iodine is a solid at standard temperature and pressure, but sublimes directly to gas phase, without any intermediate liquid phase, at only moderately higher temperatures than the standard.

Solid in solid: metal alloys. Liquid in liquid: vinegar dissolving in water. Gas in gas: air. Solid in liquid: salt dissolving in water. Liquid in solid: mercury absorbed by gold. Gas in liquid: carbon dioxide dissolving in soda. Solid in gas: smoke particles in air. Liquid in gas: water vapor in air. Gas in solid: hydrogen absorbed by palladium.

Iodine is the halogen that sublimes directly from a solid to a gas at standard pressure and temperature.
Iodine is a solid at room temperature and pressure. It sublimes directly from a solid to a gas when heated without passing through a liquid phase.
iodine is a substance that has an unusual property, it has the ability to sublimate, this means that it converts directly from a solid to a gas with no liquid stage at all. So no, no iodine will "melt" into a liquid, it will insted turn into a purple gas.
The chemical equation for the sublimation of iodine solid to iodine gas is: I2(s) -> I2(g). This represents the process in which solid iodine directly transforms into iodine gas without going through a liquid phase.
The three states of iodine are solid, liquid, and gas. At room temperature, iodine is a solid with a dark purple color. When heated, it sublimes directly from a solid to a purple-violet gas.
AnswerIodine is an element that is a shiny grey solid and can be seen subliming slightly at RTP (Room Temperature and Pressure) into a purple-pink gas. Unless in solution, it is never a liquid.
Iodine is a solid at room temperature. It sublimes directly from solid to gas without melting.
Iodine does not go through a liquid when changing phase. Carbon dioxide does not go through liquid phase. Both iodine and carbon dioxide sublime from a solid to a gas and condense from the gas to a solid.
Iodine I2
Sublimation is the process where a substance changes directly from a solid to a gas without passing through the liquid phase. In the case of iodine, when it is heated, it transforms from a solid to a purple gas without forming a liquid.
Elemental iodine is a solid. But it is a volatile solid in that chemists will use solid iodine in a chamber to "iodine stain" substances in thin layer chromatography. Thus iodine is like having a volatile solid.
At room temperature iodine is a solid halogen.
Iodine is a nonmetal but it can be found in solid forms. Iodine experiences sublimation which is the transition from solid to gas, therefore it skips the liquid form.
