- Calcium: Physical Properties --silver-grey metal. melts at 840°C, boils at 1484°C to produce monatomic gas. density 1540 kg/m^3. Conductor of electricity but a poor one com … pared to most other metals.Diamagnetic. Chemical properties -- tarnishes rapidly in air to produce a powdery, flaky oxide coating.Reacts steadily with water, giving off bubbles of hydrogen and a solution/slurry of alkaline, sparingly soluble calcium hydroxide. Flammable at high temperatures with oxygen, or air.an also burn in nitrogen to form calcium nitride or carbon dioxide to form calcium carbonate. Nearly all compounds are in oxidation state +2, and the water chemistry of calcium is dominated by the hydrated Ca(2+) ion.

Magnesium Magnesium is the ninth most abundant element in the universe. It is synthesized in large, aging stars from the sequential addition of three helium nuclei to a carbon nucleus. Magnesium is flammable, burning at a temperature of approximately 3,100 °C (3,370 K; 5,610 °F), and the autoignition temperature of magnesium ribbon is approximately 473 °C (746 K; 883 °F). 2  It produces intense, bright, white light when it burns.

Ceramide Ceramides are a family of waxy lipid molecules. A ceramide is composed of sphingosine and a fatty acid. Ceramides are found in high concentrations within the cell membrane of cells.They are one of the component lipids that make up sphingomyelin, one of the major lipids in the lipid bilayer.e novo synthesis of ceramide begins with the condensation of palmitate and serine to form 3-keto-dihydrosphingosine. This reaction is catalyzed by the enzyme serine palmitoyl transferase and is the rate-limiting step of the pathway.

Learn About Magnesium Alone, magnesium metal can be used as a desulpherizer in iron and steel production, as a deoxidizer in the thermal reduction of titanium, zirconium and hafnium, and as a nodularizer in the production of nodular cast iron.agnesium's characteristics are similar to its sister metal, aluminum. It not only has the lowest density of all the metal elements, making it the lightest, but it is also very strong, highly resistant to corrosion and easily machinable. History:

MAGNESIUM CAPRYLATE 7.6% Magnesium is an essential mineral to the human body. It is needed for bone, protein, and fatty acid formation, making new cells, activating B vitamins, relaxing muscles, clotting blood, and forming adenosine triphosphate (ATP), which is the energy the body runs on. The secretion and action of insulin also require magnesium.

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).

CALCIUM 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 850°C (1,560°F) and its boiling point is 1,440°C (2,620°F).

ATOMIC AND PHYSICAL PROPERTIES OF THE GROUP 7 ELEMENTS (THE HALOGENS) This page explores the trends in some atomic and physical properties of the Group 2 elements-beryllium, magnesium, calcium, strontium and barium.You will find separate sections below covering the trends in atomic radius, first ionisation energy, electronegativity and physical properties.s you go down the Group, the increase in nuclear charge is exactly offset by the increase in the number of inner electrons. Just as when we were talking about atomic radius further up this page, in each of the elements in this Group, the outer electrons feel a net attraction of 2+ from the centre.

It's Elemental He tasted the water and found that it tasted very bitter. He also noticed that it helped heal scratches and rashes on his skin. Epsom salt is still used today to treat minor skin abrasions. Other magnesium compounds include magnesium carbonate (MgCO 3) and magnesium fluoride (MgF 2). Magnesium carbonate is used to make some types of paints and inks and is added to table salt to prevent caking. A thin film of magnesium fluoride is applied to optical lenses to help reduce glare and reflections.
