                Antimony: the essentials

                Antimony atoms have 51 electrons and the shell structure is 2.8.18.18.5. The ground state electronic configuration of neutral antimony is [Kr].4d10.5s2.5p3 and the term symbol of antimony is 4S3/2.

                Antimony: description  

                Metallic antimony is an extremely brittle metal of a flaky, crystalline texture. It is bluish white and has a metallic lustre. It is not acted on by air at room temperature, but burns brilliantly when heated with the formation of white fumes. It is a poor conductor of heat and electricity.

                网络斗地主下载Antimony and its compounds are toxic. It is found mostly with other minerals and in stibnite.

                Antimony: history

                Antimony was discovered by Known since ancient times in unknown at not known. Origin of name: from the Greek words "anti + monos" meaning "not alone" (the origin of the symbol Sb comes from the Latin word "stibium").

                The two Antimony isotopes are used for the production of medical radioisotopes. Sb-121 can be used for the production of I-124, although this medical radioisotope is usually produced via Te-124. Sb-121 and Sb-123 can both be used for the production of I-123, although the most common production route is via Xe-124 or Te-123.

                Antimony: isolation

                Isolation: it is not usually necessary to make antimony in the laboratory as it is commercially available. Antimony is found in nature in a number of minerals including stibnite (Sb2S3) and ullmanite (NiSbS). Small amounts of native antimony have been found. Some ores are treatable under reducing conditions to form Sb2S3网络斗地主下载. The sulphide is removed to leave elemental antimony with scrap iron.

                Sb2S3 + 3Fe → 2Sb + 3FeS

                In antehr process, some ores can be heated to evolve the oxide Sb2O3网络斗地主下载 and this in turn can be reduced by charcoal in the presence of sodium sulphate, to ensure mixing, to form elemental antimony.

                2Sb2O3 +3C → 4Sb + 3CO2
