Because iodine sublimates, as do the other solid halogens. That means they go from solid to gas without becoming a liquid first.
Im pretty sure that Iodine does though not 100% sure. Are you talking about an element or a compound?
Iodine is a solid when at 25 degrees centigrade (room temperature)
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.
Iodine (I), sodium iodide (NaI), potassium iodide (KI), hydroiodic acid (HI)
Well, honey, when iodine is heated, it undergoes sublimation, meaning it goes from a solid directly to a gas without melting into a liquid first. So, technically, the equation for this process is just I2 (s) → I2 (g). Short and sweet, just like me.
Iodine is a purple-black non metal that changes to a deep purple gas when heated.
When iodine is heated, it sublimes directly from a solid to a purple gas. The gas produced is diatomic iodine molecules (I2).
The purple gas formed when heating solid iodine in a test tube is iodine vapor. Iodine sublimes directly from a solid to a gas when heated, turning into a purple gas that condenses back into solid iodine crystals when cooled.
The purple gas that forms when heating iodine crystals is called iodine vapor.
It gets further apart and turns into a pink purple colour

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.
This is also iodine, as a gas.
When iodine is heated, it sublimes from a solid state directly into a purple-colored gas. It undergoes sublimation, which means it changes from a solid to a gas without passing through the liquid state.
Purple !! :) x

A gas heated to millions of degrees would emit X-rays.
