Tellurium(IV) iodide facts for kids
Tellurium(IV) iodide, also known as tellurium tetraiodide, is a special kind of chemical compound. Think of a chemical compound as two or more different elements joined together. Its chemical formula is TeI4. This means it has one tellurium atom and four iodine atoms linked up. In this compound, tellurium is in a specific "mood" or state called its +4 oxidation state. It also contains iodide ions, which are iodine atoms that have gained an extra electron.

What is Tellurium(IV) Iodide?
Tellurium(IV) iodide is a solid substance that looks black. It's a bit like a black powder or tiny black crystals. When you heat it up, it doesn't just melt. Instead, it breaks down into two simpler substances: tellurium(II) iodide and iodine.
Properties of TeI4
This compound is known as a weak reducing agent. In chemistry, a reducing agent is a substance that helps another substance gain electrons. It's like it's "giving" electrons away. Another interesting thing about tellurium(IV) iodide is that it can conduct electricity when it's melted. Most solids don't conduct electricity well, but when this one turns into a liquid, it can.
How Tellurium(IV) Iodide is Made
Scientists can make tellurium(IV) iodide in a couple of ways. One way is to mix tellurium and iodine together and let them react. It's like baking, but with chemicals! Another way is to react tellurium with a chemical called iodomethane, which has the formula CH3I.
Other Compounds Like TeI4
Tellurium can form similar compounds with other elements from the same family as iodine. These are called halogens. Here are some examples:
