Physical 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 850Â°C (1,560Â°F) and its boiling point is 1,440Â°C (2,620Â°F).
Calcium also helps regulate cell permeability. It is also very alkaline-forming and critical for the maintenance of acid-base balance of the blood and the body tissues. Calcium is involved in the secretion of male and female hormones, cell division and the water balance of the body.It also stabilizes cell membranes, helps muscles relax, and slows nerve transmission and the heart rate. Calcium also helps prevent fluid loss from cells and from the blood.n this case, calcium becomes biounavailable. That is, an excess occurs in the tissues but it is not available to the body. It becomes essentially a toxic mineral, causing calcium deposits in the joints, arteries, kidneys, brain and elsewhere.
