Calcium is an element in the human body. It was discovered in 1808 by Humphry Davy.
Calcium is a chemical on the Periodic Table with the symbol Ca and atomic number 20. Calcium is a soft gray alkaline earth metal, it is the fifth-most-abundant element by mass in the Earth's crust. The element Calcium ion is also the fifth-most-abundant dissolved ion in seawater. Free calcium metal is too reactive to occur in nature or it is natural. Calcium is produced in supernova nucleosynthesis. Supernova nucleosynthesis is the theory of the production of many different chemical elements in Supernova explosions. The atomic mass of Calcium is 40.078. The density of Calcium is 1.55 g/L. This is the Melting point 1112 K and Boiling point 1757 K for Calcium.The shell structure …show more content…
The number of protons in Calcium is 20 and the number a neutrons is 20. The number of valence electrons in calcium are 2. Calcium isn't just used for making strong bones. It is used to make the cement on sidewalks, cheese,and removing nonmetal from different metal mixes (called alloys,) and also is used as an agent in the preparation of other metals. As you can we might be looking at Calcium and not know it. Pure calcium is actually a metal, and reacts very strongly, and sometimes it may violently explode with water and acids. The best sources of calcium in the American diet are milk, yogurt, and cheese. Nearly 72% of the calcium in the US comes from dairy foods. Calcium makes up the hard outer covering of bones in the human body, and gives them their strength. The insides of bones is very spongy, and full of holes, which makes these bones very light. There are lots of things Calcium give us. There is even more this element can do for you. Calcium plays a very important role in many bodily functions. It helps build stronger, denser bones and keeps bones healthy later in life. It also helps with the electricity in nerves, and with muscle

Calcium is one the most essential minerals in the development of human body. It is vital, because it aids in the development and maintenances of the bones in the body at it relates to human physiology. The human body needs calcium, which can be gained through food nutrients for building of strong bones and skeletal future development. The primary function of Calcium in the body is to harden the bone structure and supports the human body. Calcium is released from the internal storage in the endoplasmic…

Calcium Carbonate Cement Research Paper

Calcium Carbonate Cement The material: Calcium carbonate cement is a material that is made up of carbon dioxide (CO2) that has been converted to carbonate (CO3) and bound to minerals such as calcium and magnesium. It is a white powder-like material that can be used as an aggregate or supplementary cementitious material in construction and could substitute Portland cement. The Concept: The process of making calcium carbonate cement was developed by studying the formational process of coral reefs…

Romaji: Water and Polyacrylamide Gel Essay

IMMOBILISATION OF SACCHAROMYCES CEREVISIASE FOR THE PRODUCTION OF BIOETHANOL The major focus of this paper is the different content of immobilizing yeast. The independent variable is calcium alginate and polyacrylamide gel. The hypothesis was not stated in this article; however the purpose of this experiment was to determine if calcium alginate or polyacrylamide gel would produce ethanol at a higher rate and also the productivity of ethanol. The topic of this article was on bioethanol, specifically…

Physiological Significance of Lysophosphatic Acid Essay

articles and research studies to play an essential role as a mediator of osteoblast and osteoclast signaling. A review article by Danielle, et al summarizes evidence that discusses LPA, a bioactive phospholipid and its essential role in the interactions that occur between osteoblasts and osteoclasts. The review article suggests several ways that LPA released from osteoblasts are important mediators of bone growth, survival and calcium levels. No experiments were conducted in this paper as it was a…

Essay on Ocean acidification

chemical reactions occur that reduce seawater pH, 2 carbonate ion concentration, and saturation states of biologically important calcium carbonate minerals. These chemical reactions are termed "ocean acidification" or "OA" for short. Calcium carbonate minerals are the building blocks for the skeletons and shells of many marine organisms. In areas where most life now congregates in the ocean, the seawater is supersaturated with respect to calcium carbonate minerals. This means there are abundant building blocks for calcifying organisms to build their skeletons and shells…

Duchenne Cerebral Essay

steroid-based medication called Deflazacort to help maintain his muscle strength. One of the side effects of steroidal medication and a lack of physical activity (as a result of wheelchair use) is a loss of calcium in the bones. This may increase the risk of fractures. Jonathan takes daily doses of calcium, in conjunction with vitamin D, to keep his bones strong. Other possible treatments that may help with some aspects of DMD include physiotherapy to help maintain correct foot position, chiropractic…
