Zirconium - Wikipedia
Zirconium is a chemical element with the syol Zr and atomic nuer 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon; zar-gun, "gold-like" or "as gold")), the most important source of zirconium.[5] It is a lustrous, grey-white, strong transition metal that closely reseles

Calcium is a reactive, soft metal that is a meer of the alkaline earth elements. It frequently serves as an alloying agent for other metals like aluminum and beryllium industrial materials like cement and mortar are composed of calcium compounds like calcium carbonate .
Fluorine - Wikipedia
Fluorine, 9F. cubic. Fluorine is a chemical element with the syol F and atomic nuer 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium .

Fluorine''s special status also stems from the ''fluorine factor'', the ability of this little atom to fine-tune the chemical properties of an entire molecule. For example, replacing hydrogen with fluorine can protect drugs from degradation by metabolic enzymes, extending their active lifetimes inside the body.
