Antimony also has the unusual property that (like water) it expands as it freezes. [2] b.i. Arab alchemist Abu Musa Jabir Ibn Hayyan (721–815 CE) probably first called it antimony — ‘anti’ meaning not and ‘monos’ meaning alone because the element does not occur alone in nature (Shotyk, Krachler & Chen, 2006). (1) Identify which reactants are being oxidized (the oxidation number increases when it reacts) and which are being reduced (the oxidation number goes down). Deduce the chemical equations for these two reactions. The modified Gutzeit method can be used to determine small amounts of antimony (Harder, 2002). It's likely that Roman author Pliny gave it the name stibium, from which the modern element symbol Sb was taken, in the first century AD. It is found in nature as the minerals valentinite and senarmontite. Carefully, insert coefficients, if necessary, to make the numbers of oxidized and reduced atoms equal on the two sides of each redox couples. It always occurs in hydrated form, Sb2O5-nH2O. Antimony acts as an oxidizing agent and readily reacts with many metals to form antimonides. With time, stibine decomposes into hydrogen and metallic antimony. Two of these radioactive isotopes (antimony-124 and antimony-125) are used commercially as tracers (Emsley, 2011). 2. Possible oxidation states are +3,5/-3.

In addition to the usual form of antimony, there are two allotropes: yellow crystalline and amorphous black. Vannoccio Biringuccio, The Pirotechnia of Vannoccio Biringuccio, translated by Cyril Stanley Smith and Martha Teach Gnudi, (1990) p201. Complex ores such as livingstonite are also a major source of antimony. Like arsenic, which sits directly above it in the periodic table, the toxicity of antimony and its compounds varies according to the chemical state of the element. Antimony is mainly used metallurgically as an additive substance because its physical properties are not suitable for engineering. It also finds its way into the environment through numerous applications by human actions. He also warns against heating the antimony sulfide too strongly because this will produce a substance that "although this is very white and almost more shining than silver, it is much more brittle than glass." Antimony was discovered as an element in the 17th century although it had been in use several centuries earlier. (3) In an alternative process, the sulfide is converted to oxide and then weighed as Sb4O6. (1) It is likely that the Roman author Pliny used the name stibium in the first century AD.
