PHYSICAL PROPERTIES OF Calcium, Characteristics such as Refractive Index, Density of Calcium, Molecular Weight, Atomic Mass. The skeleton acts as a major mineral storage site for the element and releases Ca2+ ions into the bloodstream under controlled conditions. Calcium is atomic number 20 with symbol Ca on the periodic table. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Reactions are chemical properties. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. This WebElements periodic table page contains physical properties for the element calcium Calcium plays a vital role in the anatomy, physiology and biochemistry of organisms and of the cell, particularly in signal transduction pathways.
