href=\"https:\/\/byjus.com\/periodic-table\/\">periodic table<\/a>&nbsp;with the symbol&nbsp;<strong>Ca<\/strong>.<\/li><li>Calcium (Ca) is a vital element that aids our bones stay tough and capable of supporting our load.<\/li><li>Calcium is also used by our nervous system to help transmit impulses through our body.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Uses Of Calcium<\/h2>\n\n\n\n<ul><li>The element maintains the vital for bones and teeth.<\/li><li>The element assists in the movement of muscles by helping to carry messages from the brain to all parts of the body.<\/li><li>The ions of the element act as carriers of between cells in the form of multicellular life forms<strong>.<\/strong><\/li><li>The element aids in assisting hormones to release along with enzymes.<\/li><li>This element is widely used in steelmaking because it tends to readily form compounds with oxygen and sulphur.<\/li><li>Several calcium compounds find use in the food industry (as food additives) and the pharmaceutical industry.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Properties Of Calcium<\/h2>\n\n\n\n<ul><li>The element is the fifth most abundant metal in the planet\u2019s crust (4.1%).<\/li><li>Important isotopes of calcium include&nbsp;<sup>48<\/sup>Ca,&nbsp;<sup>46<\/sup>Ca,&nbsp;<sup>44<\/sup>Ca,&nbsp;<sup>43<\/sup>Ca,&nbsp;<sup>42<\/sup>Ca, and&nbsp;<sup>40<\/sup>Ca.<\/li><li>Traced in large amounts as gypsum (calcium sulfate), limestone (calcium carbonate), apatite (calcium chloro- or fluoro-phosphate) and fluorite (calcium fluoride).<\/li><li>Dissolved calcium bicarbonate is found in&nbsp;<a href=\"https:\/\/byjus.com\/jee\/hardness-of-water-types-and-removal\/\">hard water<\/a>.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Certain Facts About Calcium<\/h2>\n\n\n\n<ul><li>Since before the Greeks and Romans, humans have known about calcium and compounds that contain calcium.<\/li><li>Romans made use of lime in their concrete and termed it \u201cCalx.\u201d<\/li><li>Davy was the original chemist to separate pure calcium in 1808.<\/li><li>Once the element is refined, it would turn tougher as a
