Calcium Metal Formula, Chemical element, Calcium, information from authoritative sources.

Calcium Metal Formula, Unlike most transition metals, calcium and its compounds exhibit a low toxicity. Calcium is a chemical element; it has symbol Ca and atomic number 20. Calcium metal reacts with oxygen in the air to make a layer of calcium oxide on the outside of the metal. Chemical element, Calcium, information from authoritative sources. Humans have used calcium compounds for hundreds of years in construction, sculpture, and roads. Calcium gluconate and calcium lactate are absorbed well by pregnant women. Calcium metal was not prepared in a pure form until 1808 when English chemist Humphry Davy (1778-1829) passed an electric current through molten (melted) calcium chloride. A crystal structure containing Calcium: Part of one layer of the crystal structure of gypsum, which is a mineral that contains calcium sulfate. NIST subscription sites provide data under the NIST Standard Reference Data Program, but require an annual fee to access. Significance: Crucial in construction (cement, concrete), biology (bones and 0:13 Calcium metal burning Calcium is the third alkaline earth metal, and has similar chemistry to the rest of the group. Bond Type: Calcium typically forms ionic bonds due to its two valence electrons. Several calcium compounds find use in the food industry (as food additives) and the pharmaceutical industry. The chemical properties of its compounds can be applied to all the heavier homologs. Molecular Structure: A soft, silvery-white metal, less dense than magnesium. It is element atomic number 20 on the periodic table with the symbol Ca. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. Consider its compounds. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys. This stops further chemical reactions (passivation) until the layer is removed. The best-absorbed form of calcium from a pill is a calcium salt like carbonate or phosphate. Calcium compounds are common and abundant in the Earth's crust.
