Appearance:Silver-white pieces
Density:1.54 g/cm3 @ Temp: 20 °C
Melting Point:842 °C
Boiling Point:1484 °C
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. Molten calcium reacts explosively with asbestos cement.|Much harder than sodium, but softer than aluminum or magnesium; Brinell hardness: 17; electrical resistivity: 3.5 microohm cm @ 20 °C; specific heat: 0.149 cal/g (from 0-100 °C); reacts with water, alcohols, dil acids and halogens; forms blue color in liquid ammonia|Alkaline earth element; oxidizes in air to form adherent protective film; can be machined, extruded, or drawn|Burns with crimson flame.|Based on calcium's electronic configuration, it can have 2 oxidation states. 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.

Handling and StoragePrecautions for safe handling
NO contact with air, water or incompatible substances. PREVENT DISPERSION OF DUST. Use non-sparking handtools. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Fireproof. Dry. Well closed. Keep under inert gas. Separated from incompatible materials. See Chemical Dangers.Store in a cool, dry, well-ventilated location. Separate from water, alcohols, acids, and halogens. Immediately remove and properly dispose of any spilled material.
