The discovery of Arsenic is credited to the German philosopher Albertus Magnus, approximately in the year 1250. The exact location of this discovery however, is unknown. In his work “De Mineralibus”, he described how Arsenic could be obtained through the heating of orpiment and soap together. This notorious poison has been used by the Egyptians, Greeks, and Chinese for centuries as well.
Arsenic can be found abbreviated as “Ar” in group 15, period 4. This element has an atomic mass of thirty-three and a classification as a metalloid. At room temperature, Arsenic is in a solid state however, when heated to 616°C, it sublimes. Its melting point is at 817°C and its boiling point at 603°C.
Presently used in rat poisons, insecticides, and other
