It occurs chiefly as the gray sulfide mineral stibnite (Sb 2 … Chemical Properties. Antimony is a lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite. Antimony occurs naturally in the environment and is predominantly found in Russia, Bolivia, china, and South Africa. Antimony is a chemical element.It has the chemical symbol Sb.The symbol Sb is from the Latin name of 'stibium' for the element. It has the atomic number 51. (1) Antimony's electrical and thermal conductivity are lower than most metals' conductivities. The metal and its compounds also used in batteries, bullets, cable sheathing, flame-proofing compounds, glass, ceramics, paints, and pottery. Its atomic mass is 121.8. Antimony sulfide (Sb 2 S 3) is mentioned in an Egyptian papyrus of the 16 th century BC. The chemical properties of antimony are provided in the table below. Antimony metal is generally stable under normal conditions and does not … It is used to fireproof fabrics, paper and plastics, as a paint pigment and for many other uses. Emits toxic antimony and sulfur oxide fumes if heated to high temperatures. 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. Crystals burn with a blue flame when heated in air [Mellor 9:522 1946-47]. What is Antimony? It is easily powdered. Antimony is a brittle, fusible, crystalline solid. ANTIMONY SULFIDE presents a serious fire risk if exposed to oxidizing agents. Immediate steps should be taken to limit its spread to the environment. Antimony is used in the semiconductor industry for infrared detectors, Hall-effect devices, and diodes. Antimony exists in many allotropic forms. It occurs chiefly as the gray sulfide mineral stibnite. Antimony compounds are reduced by nascent hydrogen in acid (but not in alkaline) solution forming antimony trihydride or stibine. Toxic by inhalation and by ingestion. Antimony trioxide is a white crystalline solid.
It is found in over 100 mineral species with sulfide stibnite (Sb 2 S 3) being the main ore mineral.

It is most often found as antimony(III) sulfide. It is insoluble in water. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of the atom or less, but it ... Atomic Number Density . Antimony is metalloid, so it has some metallic properties but not enough to be classified as a true metal. Properties and reactions The most stable form of elemental antimony is a brittle, silvery solid of high metallic lustre.

Antimony exists in many allotropic forms (physically distinct conditions that result from different arrangements of the same atoms in molecules or crystals). Atomic Weight . Chemical reactions for antimony. It is generally found in two forms namely metallic form... Antimony compounds are used since ancient … Physically, it behaves like sulfur while chemically it is more metallic. The black form of this pigment, which occurs naturally as the mineral stibnite, was used as mascara and known as khol. The primary hazard is the threat to the environment. Antimony is a semi-metallic chemical element with an atomic number 51 and symbol Sb in... Latin name of Antimony is Stibium. The chemical symbol for Antimony is Sb . Color Tin-white Streak Grey Luster Metallic Cleavage Perfect Perfect and easy on {0001}, distinct on {1011}, imperfect on {1014} and indistinct on {1120}. It also does not react with cold water or with most cold acids. Density – Atomic Mass and Atomic Number Density. Reacts with concentrated solutions … Chemical Properties of Antimony. Antimony in its elemental form is a silvery white, brittle, fusible, crystalline solid that exhibits poor electrical and heat conductivity properties and can sublimate upon heating. It is a lustrous, silvery, bluish white solid that is very brittle and has a flaky texture. Antimony, a metallic element belonging to the nitrogen group (Group 15 [Va] of the periodic table). It is extracted by roasting the antimony(III) sulfide to the oxide, and then reducing with carbon. Antimony and its compounds were known to the ancients and there is a 5,000-year old antimony vase in the Louvre in Paris. A metalloid, antimony resembles a metal in its appearance and in many of its physical properties…
