Fluorine molecule
A fluorine molecule is formed by the covalent bonding of two fluorine atoms, represented by the molecular formula F₂. Although it exists as a diatomic molecule, it does not occur naturally in its elemental form due to its high reactivity. It is a highly toxic gas with strong oxidizing properties. It is effective in treating the surface of teeth, which is why fluoride compounds are commonly included in toothpaste and widely used.
