Metal elements are needed for several tasks in medicine, such as nerve impulse transmission, oxygen flow, enzyme reaction, and so on. Several medications are mixed with metal compounds to address certain deficiencies or disorders. Antacids contain elements that are often used in medicine, such as...
Selenium (Se) is a metalloid and a rare dispersing element widely distributed; its abundance in the Earth’s crust is, however,low, ranking only 70th among all chemical elements (Williams and Byers, 1936). Selenium can directly react with various metal and nonmetal elements to form assorted or...
