It can also be found as a powder.
Calcium cations (Ca2+ ) and calcium salts are among the most commonly encountered substances in water, arising mostly from dissolution of minerals. Calcium often is the most abundant cation in river water. Among the most common calcium minerals are the two crystalline forms of calcium carbonate-calcite and aragonite (CaCO 3 , limestone is primarily calci

Calcium appears as a silvery, soft metal that turns grayish white on exposure to air. Used in metallurgy.|Calcium atom is an alkaline earth metal atom. It has a role as a macronutrient.|Calcium plays a vital role in the anatomy, physiology and biochemistry of organisms and of the cell, particularly in signal transduction pathways. The skeleton acts as a major mineral storage site for the element and releases Ca2+ ions into the bloodstream under controlled conditions. Circulating calcium is either in the free, ionized form or bound to blood proteins such as serum albumin. Although calcium flow to and from the bone is neutral, about 5 mmol is turned over a day. Bone serves as an important storage point for calcium, as it contains 99% of the total body calcium. Low calcium intake may also be a risk factor in the development of osteoporosis. The best-absorbed form of calcium from a pill is a calcium salt like carbonate or phosphate. Calcium gluconate and calcium lactate are absorbed well by pregnant women. Seniors absorb calcium lactate, gluconate and citrate better unless they take their calcium supplement with a full breakfast.|Calcium is an element with atomic symbol Ca, atomic number 20, and atomic weight 40.08.|A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.Basic Info-

Water Solubility:Solubility in water: reaction
Storage Conditions:water-free area
Vapor Pressure:negligible
Experimental Properties:Moderate explosion hazard in intimate contact with very powerful oxidizing agents. ... Can develop explosive pressure in containers. ... Violent reaction with water may evolve explosive hydrogen gas. Potentially explosive reaction with alkali metal hydroxides or carbonates; dinitrogen tetraoxide; lead chloride + heat; phosphorus(V) oxide + heat; sulfur + heat.

Calcium has an electronic configuration of (Ar)4s2. The most stable electronic configuration for calcium to have is (Ar). In order for this to happen, calcium needs to lose 2 electrons giving it a +2 charge.
Air and Water Reactions:Pyrophoric ignites in air when finely divided, then burns with crimson flame [Merck 11th ed. 1989]. Calcium rapidly decomposes in water, the heat of reaction is sufficient that hydrolysis released hydrogen may ignite [Lab. Gov. Chemist 1966]. Pyrophoric hazard only exists when this material is in a powdered form. If the material is in large pieces, it is unlikely to burn or react strongly with water under normal conditions.
Reactive Group:Metals, Elemental and Powder, Active
Reactivity Alerts:Strong Reducing Agent
Reactivity Profile:Boron trifluoride reacts with incandescence when heated with alkali metals or alkaline earth metals except magnesium [Merck 11th ed. 1989]. Calcium reacts violently with acids [Lab. Govt. Chemist 1965]. Finely divided calcium burns spontaneously in chlorine at elevated temperatures [Mellor 3:637, 638, 651 1946-47]. Finely divided or massive calcium burns spontaneously in fluorine at ordinary temperatures. It is incompatible with metal oxides, alkali metal hydroxides, chlorine fluorides, dinitrogen tetraoxide, and sulfur(with sulfur reacts explosively when ignited) [Bretherick, 5th Ed., 1995].
Autoignition Temperature:1454+-18 °F (USCG, 1999)
Heat of Combustion:151.9 cal/g
Physical Dangers:Ignites in air when finely divided.
