- Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a soft gray alkaline earth metal, fifth-most-abundant element by mass in the Earth 's crust. The ion Ca 2+ is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate.Free calcium metal is too reactive to occur in nature.n chemical terms, calcium is reactive and soft for a metal; though harder than lead, it can be cut with a knife with difficulty. It is a silvery metallic element that must be extracted by electrolysis from a fused salt like calcium chloride.

- Calcium + Water Calcium is a silvery-white metal; it is relatively soft, but much harder than sodium metal. Calcium is a member of the alkaline-earth metals (Group II on the periodic table); these metals react vigorously with water, although not as violently as the Group I metals such as sodium or potassium:

It's Elemental Although calcium is the fifth most abundant element in the earth's crust, it is never found free in nature since it easily forms compounds by reacting with oxygen and water. Metallic calcium was first isolated by Sir Humphry Davy in 1808 through the electrolysis of a mixture of lime (CaO) and mercuric oxide (HgO).

Environmental impact of concrete Calcium carbonate occurs as aragonite and calcite. The carbonate minerals form the rock types: limestone, chalk, marble, travertine, tufa, and others. Calcium carbonate has been found in some mines to be 99.2% pure.alcium carbonate is a chemical compound with the formula Ca C O 3. It is formed by three main elements: carbon, oxygen and calcium. It is a common substance found in rocks in all parts of the world, and is the main component of shells of marine organisms, snails, coal balls, pearls, and eggshells.

CALCIUM Chemical properties. Calcium is a moderately active element. It reacts readily with oxygen to form calcium oxide (CaO): Calcium reacts with the halogens— fluorine, chlorine, bromine, iodine, and astatine, The halogens are the elements that make up Group 17 (VIIA) of the periodic table.hysical properties. Calcium is a fairly soft metal with a shiny silver surface when first cut. The surface quickly becomes dull as calcium reacts with oxygen to form a coating of white or gray calcium oxide. Calcium's melting point is 850°C (1,560°F) and its boiling point is 1,440°C (2,620°F).

Learn the Chemical Properties of Calcium The test has altered its chemical composition. The chemical properties of calcium are the ways it changes when it comes into contact with other substances. The two substances react to form new chemical bonds together. This creates molecules that are mixes of calcium and the other element or compound in the reaction.

Learn the Chemical Properties of Calcium Another chemical property of calcium is that, when it burns, it makes a bright reddish-yellow flame. Finally, most of the halogen elements will react with calcium simply by coming into contact with it, forming compounds. The exceptions are bromine and iodine; calcium only reacts with these two substances when heated.

Missouri Limestone In calcite, carbonate is chemically combined with calcium to form calcium carbonate (formula CaCO3). In dolomite, carbonate is chemically combined with calcium and the element magnesium (symbol Mg) to form calcium-magnesium carbonate (formula CaMg(CO3)2). In dolomite there is one magnesium atom for every calcium atom.oth are calcium-bearing carbonate minerals, meaning that they contain the chemical elements calcium (symbol Ca), carbon (symbol C) and oxygen (symbol O). Each carbon atom is combined with three oxygen atoms to form what is called carbonate (formula CO3).

Calcium hydroxide For (Ca(OH)2)(aq), see limewater. For the application of slaked lime as a wall colorant, see limewash. Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca(OH)2. It is a colorless crystal or white powder and is obtained when calcium oxide (called lime or quicklime) is mixed, or slaked with water. It has many names including hydrated lime, caustic lime, builders' lime, slack lime, cal, or pickling lime. Calcium hydroxide is used in many applications, including food preparation.

Calcium: the essentials Calcium as the element is a grey silvery metal. The metal is rather hard. Calcium is an essential constituent of leaves, bones, teeth, and shells. Calcium is the fifth most abundant element in the earth's crust and makes up more than 3% of the crust. Calcium does not occur as the metal itself in nature and instead is found in various minerals including as limestone, gypsum and fluorite. Stalagmites and stalactites contain calcium carbonate (CaCO3).
