Iodine is a chemical element; not a mixture, not a compound.
Iodine is an element, not a compound or mixture. It is a non-metal that exists as a solid at room temperature and is commonly used in iodized salt for nutritional purposes.
They are homogeneous. But they are not a mixture, so they are a pure substance
Iodine crystals can be removed from a mixture by sublimation, where the crystals are heated to turn directly into vapour without melting. The vapour can then be condensed back into solid iodine crystals. This technique allows for the separation of iodine from other components in the mixture.
Iodine is an element, so a pure substance, not a mixture, (so even not homogeneous).
One method to separate iodine crystals from a mixture of iodine and sand is by using sublimation. Heat the mixture, and the iodine will sublimate (turn into gas) leaving the sand behind. The iodine gas can then be collected and cooled to form iodine crystals.

Water is the compound. Iodine and calcium are elements, and air is a mixture.
Betadine is a compound. It is composed of the chemical povidone-iodine, which is a complex of the polymer povidone (polyvinylpyrrolidone) and the element iodine.
Iodine crystals are a pure substance.

Iodide is an ion formed from the element iodine, so it is not a compound.
