Calcium Element Facts Interesting Facts about Calcium. Calcium is the most abundant of the metallic elements in the human body. The average adult body contains about 1 kg or 2 lb of calcium, 99% of which is in the bones and teeth. Only oxygen, carbon, hydrogen and nitrogen are more abundant in our bodies than calcium.

What is the formula of calcium fluoride? The formula for calcium fluoride is #CaF_2#. Calcium is an Alkaline Earth Metal in the second column of the periodic table. This means that calcium has 2 valence electrons it readily gives away in order to seek the stability of the octet. This makes calcium a #Ca^(+2)# cation. Fluorine is a Halogen in the 17th column or #p^5# group. Fluorine has 7 valence electrons. It needs one electron to make it stable at 8 electrons in its valence shells. This makes fluorine a #F^(−1 )# anion. Ionic bonds form when the charges between the metal cation and non-metal anion are equal and opposite. This means that two #F^(−1)# anions will balance with one #Ca^+2# cation. This makes the formula for calcium chloride, #CaF_2#. I hope this is helpful.

Calcium chloride Calcium chloride. Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a colorless crystalline solid at room temperature, highly soluble in water. Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl2(H2O)x, where x = 0, 1, 2, 4, and 6. These compounds are mainly used for de-icing and dust control. Because the anhydrous salt is hygroscopic, it is used as a desiccant.
