Calcium is an alkaline metal and its syol is Ca. Iodine is a halogen and its syol is I. There are two atoms present in the valence shell of calcium and calcium loses two electrons to become stable. Therefore, the valency of calcium is +2. Iodine has seven
Magnesium is a white, lustrous metal which is fairly soft and ductile (e.g. magnesium ribbon), it tarnishes somewhat in moist air, a film of the oxide, MgO, being formed. On heating in air, magnesium burns with a brilliant light forming both the oxide and the nitride, MgN 2 .
Magnesium - Health Professional Fact Sheet
Magnesium supplements are available in a variety of forms, including magnesium oxide, citrate, and chloride [2,3]. The Supplement Facts panel on a dietary supplement label declares the amount of elemental magnesium in the product, not the weight of the entire magnesium-containing compound.
The metal has a silvery color, is rather hard, and is prepared by electrolysis of the fused chloride to which calcium fluoride is added to lower the melting point. Chemically it is one of the alkaline earth elements; it readily forms a white coating of nitride in air, reacts with water, burns with a yellow-red flame, forming largely the nitride.
