Calcium is a silvery metallic element that must be extracted through electrolysis from calcium chloride. Once produced, it rapidly forms an oxide coating when exposed to air and burns brightly when lit. Calcium-40 is created in large, hot stars through the process of silicon burning and the fusion of argon and helium atoms. Calcium is essential for animal and plant nutrition and participates in biochemical reactions like building skeletal systems. The recommended adequate daily intake of calcium varies depending on age.

In chemical terms, calcium is reactive and soft for a metal . It is a silvery metallic element that must be extracted by electrolysis from a fused salt like calcium chloride. Once produced, it rapidly forms a gray-white oxide and nitride coating when exposed to air. In bulk-form , the metal is somewhat dif鍖cult to ignite, more so even than magnesium chips; but, when lit, the metal burns in air with a brilliant high- intensity orange-red light.
Number of Energy Levels: 4 First Energy Level: 2 Second Energy Level: 8 Third Energy Level: 8 Fourth Energy Level: 2
Nucleosynthesis Calcium-40 is created in extremely large and hot (over 2.5 109 K) stars, as part of the silicon-burning process in which alpha particles are added to silicon atoms. The process fuses an atom of argon and an atom of helium: 36Ar + 4He = 40Ca
Recommended adequate intake for calcium: Age Calcium (mg/day) 06 months 200 712 months 260 13 years 700 48 years 1000 918 years 1300 1950 years 1000 5170 years (male) 1000 5170 years (female) 200 1 71+ years
Six facts about calcium 1.Calcium isn't found free in nature, but it can be puri鍖ed into a soft silvery-white alkaline earth metal. 2.Calcium is the 5th most abundant element in the Earth's crust, present at a level of about 3% in the oceans and soil. 3.The element is essential for animal and plant nutrition. Calcium participates in many biochemical reactions, including building skeletal systems and moderating muscle action. 4.Vitamin D is essential for calcium absorption by the human body. Vitamin D is converted to a hormone which causes intestinal proteins responsible for calcium absorption to be produced. 5.While calcium and its compounds are not considered to be toxic, ingesting too many calcium carbonate dietary supplements or antacids can cause milk-alkali syndrome, which is associated with hypercalcemia sometimes leading to fatal renal failure. Excessive consumption would be on the order of 10 g calcium carbonate/day, though symptoms have been reported upon ingesting as little as 2.5 g calcium carbonate daily. 6.The element name "calcium" comes from the Latin word "calcis" meaning "lime".
Name Origin: Latin calx, ancient name for lime Type: Alkaline Earth Metal Neutrons: 20 Discovered: 1808 Discoverers: Isolated and identi鍖ed by Sir Humphry Davy (UK).
