It is also an biologically essential substance found in teeth, bones, and shells. It frequently serves as an alloying agent for other metals like aluminum and beryllium, and industrial materials like cement and mortar are composed of calcium compounds like calcium carbonate. Calcium is a reactive, soft metal that is a member of the alkaline earth elements. In its elemental form, calcium has a dull gray-silver appearance. It is the fifth most abundant element in the earth's crust and can be found in minerals such as dolomite, gypsum, plagioclases, amphiboles, pyroxenes and garnets. Calcium was discovered and first isolated by Sir Humphrey Davy in 1808. The calcium atom has a radius of 197 pm and a Van der Waals radius of 231 pm. The number of electrons in each of Calcium's shells is and its electron configuration is 4s 2. Calcium (atomic symbol: Ca, atomic number: 20) is a Block S, Group 2, Period 4 element with an atomic weight of 40.078. m molality of the solute in mol solute/kg solvent. The potential for a pharmacokinetic interaction exists with the co-administration of CYP2D6 inhibitors which may increase the risk with increased exposure to dextroamphetamine saccharate, amphetamine aspartate monohydrate, dextroamphetamine sulfate, and amphetamine sulfate extended-release capsules. K f molal freezing point depression constant or cryoscopic constant in ☌ kg/mol. Thin Film Deposition & Evaporation Materials To find the temperature change elevation of a solvent by a solute, use the freezing point depression equation: T iK f m.You may report side effects to FDA at 1-80.
