Bone is made by Calcium

Calcium is the 20th element, its electron configuration is [Ar]4s². The element symbol of Calcium is Ca and its chemical series is alkaline earth metals. The element Calcium’s mass is 40.078, and it basically has 20 neutrons and 20 protons.

Calcium can not be found as a pure element from natural sources. It is an important nutritional element that our body requires, and deficiencies cause a disease called tetany. Because of that reason there are many daily calcium products that has calcium.[1]

Properties

Calcium, atomic number 20

The word Calcium is came from the word Clax which means lime in Latin. In 1808, Calcium was first purified by the creation scientist Sir Humphry Davy. Davy isolated pure Calcium from calcium chloride (a compound of Chlorine and Calcium). And also his research showed that lime is a part of an oxide of calcium. [2]

Occurrences

Calcite, sedimentary mineral

An element Calcium is from the earth’s minerals such as sedimentary rocks which is contains a lot of mineral sources. The sedimentary rocks include Gypsum and Calcite, and those are not naturally found in elemental state. Nowadays, formerly produced calcium is made by electrolysis of anhydrous, and pure calcium is usually made by heating lime with Aluminum. [3] [4]

Some examples of sedimentary minerals

*Actinolite *Adelite *Allanite *Alstonite

*Andesine *Calcite *Calderite *Cancrinite

*Gaylussite *Glauberite *Glaucochroite

Uses

Milk, daily calcium product

The human body contains many parts that are made from Calcium. Basically, science says the human's body is 2% calcium and it contains parts such as skulls and teeth. Because of that reason Calcium is very important element that our body requires. Especially to the growing children, the element calcium effects to their height and bones. The human usually takes their daily calcium from milk products. And to use calcium in human body, it also requires Vitamin D which helps human to absorb the calcium from foods. [5]

Calcium Products

Calcium is the element that can't find in natural source. Because of that reason there are many calcium products.

*Milk products

Milk is one of the calcium products that contain calcium, protein, vitamin C, and other good sources. Cow’s milk contains twice more nutrition than human’s milk. Because of its good nutrition, we often use milk in our daily products. For example bread, cake, yogurt, and fresh milk contain milk. [6]

*Calcium Agent

Calcium drug, that is made for a people who needs high amounts of calcium. It usually used by old poeple who has arthritis; inflammation of a joint.

Tetany

Tetany is a disease caused by a definciency of calcium, potassium, and magnesium. Insufficient nutrition of this types produces a mineral imbalance that can remain undetected for a long time because they often cause symptoms similar to asthma. It can cause shortness of breath, nausea, vomitting, a tingling sensation, and even death. The condition is cured by ingesting Calcium and vitamin D; for calcium absorption.[7]
