From a mineralogical perspective, fluorite is an evaporite mineral that contains one calcium ion and two fluorine ions. Calcium may also be substituted partially accounting for different colours of the mineral but it is usually purple.

What is the chemical formula for hydrogen fluorite?

There is no such ion as 'fluorite'. Al the halogen anions end in '----ide' . Notice the 'd' for the 't'. As with all halogen anions (halides) the formula is ' X^(-) ' . 'X' being the given halogen. However the chemical formula for hydrogen fluoride is ' HF '.


What does fluorite smell like?

Fluorite is normally odourless. However there is one location, Wölsendorf in Bavaria where there mineral is radioactive and this causes inclusion of elemental Fluorine to occur in the crystals. On fracture chemical reactions between the air and this Fluorine cause the formation of "Ozone" (which smells of electric sparks). This variety of Fluorite is therefore called Antozonite or "Stinkspar" .Also Fluorite crystals are sometimes oiled with mineral oils to make them appear more transparent for sale and these crystals can smell oily.


The color of fluorite changes due to what?

The color of fluorite changes due to impurities in its chemical composition. Trace amounts of different elements such as iron, yttrium, or europium can cause fluorite to exhibit a range of colors, from purple and blue to yellow and green. The presence of these impurities alters the way the crystal absorbs and reflects light, resulting in varied coloration.


Is fluorite harder than calcite?

Yes, fluorite is harder than calcite. Fluorite has a hardness of 4 on the Mohs scale, while calcite has a hardness of 3. This means that fluorite can scratch calcite, but calcite cannot scratch fluorite.


Will fluorite scratch a penny?

no because fluorite is softer than a penny
