The presence of antimony in historical artifacts indicates it was known to ancient civilizations combined with sulfur in stibnite (sb 2 s 3) it was used in egyptian cosmetics four or five thousand years ago, as a black eyeliner (1) 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. Antimony (sb) has an atomic number of fifty-one, with fifty-one protons in the nucleus it is a highly brittle, bluish-white, semi-metallic element antimony was used in ancient egypt as a form of eyeliner (kohl) other items made of antimony have been found dating back to 3000 bc in chaldea (iraq. 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.
A metalloid, antimony has four allotropic forms the stable form of antimony is a blue-white metalloidyellow and black antimony are unstable non-metals antimony is used in flame-proofing, paints, ceramics, enamels, a wide variety of alloys, electronics, and rubber. This table has links to all the properties of antimony included within webelements follow the link to definition of property or link to data for property of the element antimony link to definition of property. Stibnite has been periodically mined since the 1800s for gold and antimony, a metal used in batteries and flame retardant bolder, 24 sep 2017 by adding lead, antimony, copper, manganese and other natural elements, pieces could be made to replicate lapis lazuli, carnelian,. Antimony and many of its compounds are toxic antimony is a chemical element with symbol sb (from latin stibium) atomic number 51 periodic table rsc periodic element 51 antimony url q webcache.
Antimony is not an abundant element but is found in small quantities in over 100 mineral species it is most often found as antimony(iii) sulfide it is extracted by roasting the antimony(iii) sulfide to the oxide, and then reducing with carbon.

Antimony (latin: stibium) is a chemical element with symbol sb and atomic number 51 a lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (sb2s3) it was established to be an element around the 17th century. Element antimony - sb comprehensive data on the chemical element antimony is provided on this page including scores of properties, element names in many languages, most known nuclides of antimony common chemical compounds are also provided for many elements.
Antimony (sb, atomic number 51) is a toxic chemical element it is classed among the group of metalloids metalloids are elements that are neither purely metal nor non-metal other metalloids include boron, silicon, germanium, arsenic, and tellurium. Antimony is widely used in alloying to increase hardness and mechanical strength antimony is used in the semiconductor industry for infrared detectors, hall-effect devices, and diodes the metal and its compounds also used in batteries, bullets, cable sheathing, flame-proofing compounds, glass, ceramics, paints, and pottery. Antimony is a metallic element that has the atomic symbol sb, atomic number 51, and atomic weight 12175 it is used as a metal alloy and as medicinal and poisonous salts. A metalloid element having many forms, the most common of which is a hard, very brittle, shiny, blue-white crystal it is used in a wide variety of alloys, especially with lead in car batteries, and in the manufacture of flameproofing compounds.
Description named from the greek words meaning “not alone”, antimony is a metalloid element that primarily is found as a very brittle bluish-white metallic substance. Antimony makes up 02 parts per million of the earth's crust, making it the 63rd most abundant element there the soils contain 1 part per million of antimony on average, and seawater contains 300 parts per trillion of antimony on average. Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 205 in accordance with periodic trends, it is more electronegative than tin or bismuth , and less electronegative than tellurium or arsenic. Antimony stars, formed when antimony metal cools in a circular pot, were popular with the alchemists this is a very high-tech variation: it was made (and used) as a sputtering target i'm not sure why someone would want an antimony sputtering target (used to coat something with antimony in a high vacuum chamber.
Antimony is a semimetallic chemical element which can exist in two forms: the metallic form is bright, silvery, hard and brittle the non metallic form is a grey powder antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis. The ancient egyptians used it as makeup and today we use it in many ways, “it” is the element antimony discovered by the ancients, this element serves many purposes (it is no longer used as eyeliner, like it was for them), but also has many negative effects on people and the environment.
The element antimony has an atomic number of 51, and a chemical symbol of 'sb', to honor its known origins in the ancient, classical latin and earlier, ancient, classical greek languages. Antimony chemical element sign with atomic number and atomic weight chemical element of periodic table molecule and communication background connected lines with dots distress grunge texture jegas ra 2017-10-18 fotolia indian antimony for the eyelids stick with antimony eyeliner. The pure element antimony is produced from the ore by roasting it to form the oxide, then reducing the oxide with carbon or iron often a flux of sodium sulfate or sodium carbonate is used to prevent loss of molten antimony by evaporation.
