Valentinite facts for kids
Valentinite is a special kind of mineral that looks like a crystal. Its scientific name comes from its chemical makeup, which is antimony trioxide (Sb₂O₃). You can find this mineral in places where other antimony minerals have changed over time.

What is Valentinite?
Valentinite is a mineral that forms naturally in the Earth. It's a specific type of antimony trioxide, which is a chemical compound made of antimony and oxygen. This mineral is named after its chemical formula, Sb₂O₃.
How Hard is Valentinite?
To find out how hard a mineral is, scientists use something called the Mohs scale of mineral hardness. This scale helps us compare how easily one mineral can scratch another. Valentinite is not a very hard mineral. On the Mohs scale, it ranks between 2.5 and 3. This means it's about as hard as a copper penny or a fingernail.
What Does Valentinite Look Like?
Valentinite usually appears colorless, meaning you can see through it, or it can be white. It often has a shiny, almost diamond-like look. To describe how heavy it feels compared to water, scientists use something called specific gravity. Valentinite has a specific gravity of 5.76. This means it's quite dense and feels heavier than many other minerals of the same size.
How Does Valentinite Form?
Valentinite is created when another mineral called stibnite goes through a process called oxidation. Think of oxidation like when iron rusts; it's a chemical reaction with oxygen. When stibnite, which is an antimony sulfide mineral, comes into contact with air and water, it can change and form valentinite. This often happens in the upper parts of mineral deposits where there's plenty of oxygen.
