Block Calcium Research Paper

The element calcium’s name first originated from the Latin name “calx” which means “lime”. It was first discovered in England during the year 1808 by Sir Humphry Davy. He was able to separate calcium into a pure metal by doing an electrolysis process on a mixture of lime HgO, which is mercuric oxide. However, Sir Humphry Davy was not able to do this until after he found out Berzelius and Pontin electrolysed lime into mercury which constructed calcium amalgam. Although he discovered calcium in 1808, calcium metal was not available in large amounts until the beginning of the twentieth century. Before the autumn of 1808, John Dalton, an Englishman, explained the results of his own studies by supposing matter is composed of atoms. He supposed that
It has the atomic number twenty and the relative atomic mass of 40.078. The standard state of calcium, which means the reference point used to calculate the properties in different conditions, is solid at 298 K. This element is a silvery white and classified as metallic, which means it resembles a metal or metals. On the periodic table, the element calcium is located in group two. Group two is the alkaline earth metals, which means calcium is an alkaline earth metal. Also, on the periodic table it is located in period four. The block calcium is in is the s-block. The elements in the s-block are located in the first two periodic table groups. The electron shell structure for calcium are 2.8.8.2. For calcium, the CAS registry ID, which is a unique numerical identifier given to elements by the Chemical Abstracts Service, otherwise known as the CAS, is 7440-70-2. Calcium metal is now easily accessible commercially, so there is no need to make it in the laboratory. However, it can be made by the electrolysis of molten calcium chloride (CaCl2). Calcium chloride is manufactured by the action of hydrochloric acid upon calcium carbonate. In the Solway process used to make sodium carbonate, calcium chloride is a byproduct. Calcium can also be made through the reduction of CaO with aluminum or of CaCl2 with sodium
