8. Ask yourself, do I want to have strong, able bones, or do I want to be crippled beyond help? Do you want to have healthy, white teeth, or do you want to lose all of them to rotting? Ask yourself, do I want to have strong, able bones, or do I want to be crippled beyond help? Do you want to have healthy, white teeth, or do you want to lose all of them to rotting?

9. Health Contributions  As you may have guessed, calcium plays a pivotal role in bone formation and strength  Anyone pursuing a physically strenuous career or athletic activity will be able to excel with calcium! NOTE- All humans need calcium to avoid potential osteoperosis

10.  Results from a recent study conducted by the Cochrane Foundation, have shown that calcium may help to prevent colon cancer  Is it worth forgoing a purchase of calcium and suffering the consequences? NO - Be safe and ensure your health!

11. Compounds »We live in an age of skyscrapers and cement monoliths…how can such large buildings be held together and not collapse? Calcium! In compound, it can form: Calcium Carbonate (CaCO 3 ) used in cement Calcium Oxide/Lime (CaO) used in glass

12. Defense RAs stated, Calcium can support many diverse applications, including military needs: RCalcium Phosphide(Ca 3 P 2 ) used in flares and torpedoes  Calcium Permanganate (Ca(MnO 4 ) 2 ) used primarily in liquid rocket propellant RAs stated, Calcium can support many diverse applications, including military needs: RCalcium Phosphide(Ca 3 P 2 ) used in flares and torpedoes  Calcium Permanganate (Ca(MnO 4 ) 2 ) used primarily in liquid rocket propellant

13. Teaching Applications / Industrial corporations that supply schools their chalk all produce it with calcium / Calcium Sulfate (CaSO 4 ) in conjunction with two Dihydrogen Monoxide (2H 2 O) molecules forms chalk / Industrial corporations that supply schools their chalk all produce it with calcium / Calcium Sulfate (CaSO 4 ) in conjunction with two Dihydrogen Monoxide (2H 2 O) molecules forms chalk

14. Similarities  Calcium can accurately be compared to strontium  Both of these elements are widely used in fireworks and lighting sources  Calcium can accurately be compared to strontium  Both of these elements are widely used in fireworks and lighting sources

15. Strontium and Calcium both are Alkaline earth Metals and have two Valence electrons They are in successive Periods, which make them different from the rest of the group They are also the first two elements with a “d” suborbital Their atomic emission spectra are similar, allowing them to burn reddish/orange Other chemical and physical properties are very similar i.e. electronegativity, ionization energy, boiling point, etc.

16. Interesting Fact Calcium’s many uses are very interesting to me, however, geochemical cycling stand out –When tectonic plates shift, calcium rocks are exposed –Calcium eventually runs off into the ocean reacting with CO 2 to form limestone Calcium’s many uses are very interesting to me, however, geochemical cycling stand out –When tectonic plates shift, calcium rocks are exposed –Calcium eventually runs off into the ocean reacting with CO 2 to form limestone

17. Pricing  $3.50 per pound  This price is a steal! Not only can it be used is a multitude of different fields, it greatly aids human life! Even in a time of recession, getting calcium to you for a low price is my goal  $3.50 per pound  This price is a steal!
