Thallium(I) fluoride, also known as thallous fluoride, is a special chemical compound. Its chemical formula is TlF. This means it's made of one thallium atom and one fluoride atom joined together. The thallium in this compound has a charge of +1, which chemists call its +1 oxidation state.
What is Thallium(I) Fluoride Like?
Thallium(I) fluoride is a solid substance that looks like white crystals. It can easily dissolve in water, much like sugar dissolves in your drink! It also dissolves a little bit in ethanol, which is a type of alcohol. If it's left out in humid air, it can absorb a small amount of water.
How is Thallium(I) Fluoride Made?
Scientists can create thallium(I) fluoride by mixing two other chemicals. They react either thallium(I) oxide or thallium(I) carbonate with hydrofluoric acid. When these chemicals meet, they combine to form thallium(I) fluoride.
