Full Answer

Fluorine is classified as a nonmetal and is a halogen. It is the most reactive and electronegative element, meaning that it attracts electrons toward itself. It appears pale yellow as a gas and is corrosive. Fluorine reacts with most organic and inorganic substances. It is unusual for fluorine to be used in its pure form, but compounds of fluorine are used in toothpaste, pharmaceuticals and tap water and to prevent tooth decay.

    Where can sodium be found?

    A:

    While sodium is one of the most abundant elements in the crust of the Earth, About.com indicates it never exists in its elemental form. It is highly reactive and forms many compounds, including sodium chloride, or table salt. The most common form of sodium chloride on the Earth is halite, a mineral that miners remove from large mines. The rock salt from these mines remains from the evaporation of oceans.
