Here's why:
* Solid Iodine: Iodine is a non-metallic element that exists as a dark grey solid at room temperature.
* Sublimation: When heated, iodine undergoes sublimation, a process where it transitions directly from a solid to a gas without passing through the liquid state.
* Purple Vapor: The iodine vapor produced is a distinctive purple color, making it easy to identify.
Important Note: While iodine is a fascinating element, it is important to handle it with care. Iodine vapor can be irritating to the eyes, skin, and respiratory system.
