Antimony

Most web sources define antimony as a metallic element that is having four allotropic forms that are used in a wide variety of alloys. The compound is commonly found as stibnite. It is defined as a chemical element associated with the symbol sb, that stands for stibium and it has an atomic number 51. Stibnite is also referred to as antimonite and it is a sulfide mineral that has the formula sb2s3.

It is described as a soft grey compound that has a brilliant luster and it crystallizes in an orthorhombic space group. The abbreviation ‘sb’ is taken from stibnite. Various other sources define it with the symbol sb,  atomic number 51 and  atomic mass 121.75 amu. It has been used for thousands of years.

In pure metallic form antimony is quite brittle. The material has a wide variety of applications as it is used in batteries, alloys and in the creation of paints and enamels. The compound has a CAS number 7440-36-0 and it is a metalloid element that is a commonly silvery white, crystalline and brittle. It has applications, where it is used in a wide variety of alloys and semiconductors.

Some of the characteristics of that are described depict the chemical element as a silvery gray, lustrous substance that is commonly available as sulfide mineral stibnite.

Most of them have been described as fire retardants and therefore they are widely used in the production of fire proof products. Alloys that are derived from it have widespread use in the production of solder and ball bearings. According to the definition, the physical properties of the chemical element sb include that it is a soft metal and there are four allotropes of it.

The three stable types of it include explosive, yellow and black. This kind of antimony may be brittle to touch and appears silvery white shiny metal.According to information, it has been found that the yellow isotope is the most unstable type. It is generated by the oxidation of stibnite. When this isotope of it is exposed to ambient light, it transforms into stabler black allotrope.

Symbol

The chemical antimony symbol is ‘sb’ and the atomic number is 51. It is described as a brilliant grey metalloid that is naturally found in nature, in the form of sulfide mineral stibnite. According to historical evidence, the antimony symbol ‘sb’ is not found alone in nature and is identified in the form of compounds and was commonly referred to as a metal.

It may not be abundantly found in the nature, but it may be found in over one hundred mineral species.This is commonly found in native regions where it is present as sulfide stibnite. Some of the common properties associated with the antimony symbol ‘sb’ include that it is a poor conductor of heat and electricity and most of its compounds are toxic.

This chemical compound has widespread application in the production of various semiconductor technologies, that is used for making infrared detectors.It is also used in making diodes and Hall Effect devices. According to various sources, the alchemy consists of multiple symbols. In the ancient times the symbol referred to the wolf that represents man’s free spirit. It also refers to the innate animal nature associated with human beings.

Facts

According to facts, it is an element located in the fifth row of the P block element in the periodic table. The element is represented by the symbol sb and it has an atomic number 51.

The physical properties of it include twelve isotopes of antimony.Only two of the isotopes are found to be stable while the rest of the isotopes are highly radioactive. In certain cases the half life of the radioactive elements varies from fifteen minutes to sixty days. One of the stable types can be derived from ores.

The chemical properties describe it as a metalloid that is neither a metal or otherwise and it has a melting point 630.0 degrees centigrade. In crystalline form is rhombohedral in structure and the metal has been found to be insulator to thermal as well as electrical conductivity.

Some of the facts on precaution include that it can lead to poisoning that may cause various symptoms that are similar to that of arsenic poisoning. Some of the symptoms associated with this condition include headache, vomiting, dizziness and body pain. The individual may also suffer from recurrent vomiting and it is a serious condition that can be fatal, if untreated.

Uses

Most common uses of it are in the form of antimony trioxide, that has fire retardant properties. Thus, it is widely used in the production of commercial as well as domestic flame proofing products. There are uses of it, as it is used in making children’s clothing, aircraft, automobile seat covers and toys. There are many uses of it in the production of fiberglass composites where it is used as an additive to polyester resins n order to produce light aircraft engine covers.

The resin containing the agent will burn when it is exposed to fire, but it will immediately extinguish itself due to its fire retardant nature. There are uses of it, but almost half of its production is used in the making of fire proofing compounds. Other uses of it include the production f polymer polyethyleneterephthalate that is used as an additive in some glasses.

In this case it serves as an oxidizing agent that is used in the removal of microscopic bubbles. This is widely used in the production of Television screens. In the field of medicine, it is used as emetics that are mainly applied in the treatment of different protozoan diseases. There is antimony potassium tartrate, that is used is an antischistomosal drug that is subsequently replaced by praziquantel.

Antimony pentachloride

The IUPAC name for it is antimony (V) chloride and it is also referred to by other names like  quintachloride or perchloride. The chemical compound is described as a highly toxic and corrosive substance that easily fumes on exposure to moist air. It is prepared by passing chlorine gas into molten trichloride.

Some of the general properties of this include that it is a colorless or yellow oily liquid. It is hygroscopic and solidifies easily after absorbing moisture. It has widespread application in the field of chemical analysis. It is mainly used in the analytical testing for cesium and alkaloids. It is widely used for dyeing and also applied as an intermediate in chemical synthesis of various complex compounds.

It is also used as a strong oxidizing agent. It is soluble in chloroform and dichloromethane that is commercially available in solution form. When it is exposed to water, it develops a strongly acidic solution that mainly comprises of hydrochloric acid that is caused due to the process of hydrolysis of the chemical compound. This agent has been found to be highly soluble in hydrochloric acid and other solutions that contain the chloride ion. Thus the hydrolysis in the presence of excess of water.

It is also referred to as pentaflouridoantimony. The IUPAC name for it is antimony (v) fluoride. When present in gaseous mode, it assumes a trigonal bipyramidal structure that has point group symmetry. The chemical agent has a more complicated structure when it is present in liquid or solid state.

The liquid is comprised of polymers, where each molecule is present in octahedral form. The crystalline material is in the form of a tetramer and the sb-F bonds are 2.02 A, and the remaining fluoride bonds may be radiating from the octahedral rings. It compounds are monomeric when present in solid and liquid states. Antimony pentafluoride enhances the oxidizing power of fluoride, and this process is referred to as oxidation of oxygen.

It also produces fluorine gas from it. This can be explained by the driving force, that is generated by the strong affinity of antimony towards fluorides and thus as a result of this property it is mostly used in the production of super acids.

According to the various safety measures that are applied while handling it, this may react violently with various other compounds, thus releasing the dangerous hydrogen fluoride. When exposed to the skin and eyes, it may cause irritation.
