sulfur element or compound brainly

One is the orthorhombic (often improperly called rhombic) form, α-sulfur. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl). An element is a material that consists of a single type of atom. In underground deposits of very pure sulfur that are present in domelike geologic structures, the sulfur is believed to have been formed by the action of bacteria upon the mineral anhydrite, in which sulfur is combined with oxygen and calcium. Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a … Sulfur (in British English: sulphur) is a chemical element with the symbol S and atomic number 16. The history of sulfur is part of antiquity. It's necessary for life, yet some of its compounds are toxic. answers The following elements that can form acidic compounds are the following: silicon, arsenic. B. Ionic Bond. A chemical element that is naturally present in the human body, sulfur is also found in a number of foods (such as garlic, onions, eggs, and protein-rich foods) and is necessary for the synthesis of the essential amino acids cysteine and methionine. Articles from Britannica Encyclopedias for elementary and high school students. No, sulfur is an element and sulfur dioxide is a gaseous compound. We might expect sulfur to form organic compounds related to those of oxygen, and indeed it does. Seawater contains about 0.09 percent sulfur in the form of sulfate. Heated - it is compound because if they were heated it formed compound which is iron sulfide 4.Sodium bicarbonate-A compound because sodium bicarbonate is composed of four element which is sodium, hydrogen, carbon and oxygen. Upon vaporization, cyclic molecules (S8 and S6) are formed again; at about 900 °C (1,652 °F), S2 is the predominant form; finally, monatomic sulfur is formed at temperatures above 1,800 °C (3,272 °F). Sulfur is an element. The variations in both colour and viscosity are considered to result from changes in the molecular structure. The liquid then assumes the high viscosity characteristic of such structures. Another of the crystalline S8 ring allotropes is the monoclinic or β-form, in which two of the axes of the crystal are perpendicular, but the third forms an oblique angle with the first two. Sulfur (S), also spelled sulphur, nonmetallic chemical element belonging to the oxygen group (Group 16 [VIa] of the periodic table), one of the most reactive of the elements. Because sulfur is in the same group (6A) of the periodic table as oxygen, the two elements have some similar properties. The beginnings of practical and industrial uses of sulfur are credited to the Egyptians, who used sulfur dioxide for bleaching cotton as early as 1600 bce. Underground deposits of sulfur associated with salt domes in limestone rock provide a substantial portion of the world’s supply of the element. Making Connections 1. S8- 8 sulfur atoms.

Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements. On the basis of the finding that certain meteorites contain about 12 percent sulfur, it has been suggested that deeper layers of Earth contain a much larger proportion. decidis formed when on seid and boxe rench17. Sulfur (in British English, sulphur) is a chemical element with the symbol S and atomic number 16. Prehistoric humans used sulfur as a pigment for cave painting; one of the first recorded instances of the art of medication is in the use of sulfur as a tonic. Omissions? ρ-sulfur is unstable, eventually reverting to orthorhombic sulfur (α-sulfur). The reaction can be used to illustrate elements, mixtures and compounds. Many important metal ores are compounds of sulfur, either sulfides or sulfates. A second general allotropic class of sulfur is that of the eight-membered ring molecules, three crystalline forms of which have been well characterized. Just above its melting point, sulfur is a yellow, transparent, mobile liquid. Updates? The periodic table is made up of 118 elements. In the rhombohedral allotrope, designated ρ-sulfur, the molecules are composed of rings of six sulfur atoms. Some important examples are galena (lead sulfide, PbS), blende (zinc sulfide, ZnS), pyrite (iron disulfide, FeS2), chalcopyrite (copper iron sulfide, CuFeS2), gypsum (calcium sulfate dihydrate, CaSO4∙2H2O) and barite (barium sulfate, BaSO4). Elements are the simplest complete chemical substances. 3. This reaction can be carried out as a demonstration or class experiment in a well ventilated laboratory … true or false​, PASAGOT NLANG SANA PDND:DNKDKEnkeekeoeneke. Sulfur crystals from Sicily (greatly enlarged). If enough time is allowed for this transition to occur completely, further heating causes melting to occur at 118.9 °C (246 °F); but if the α-form is heated so rapidly that the transformation to β-form does not have time to occur, the α-form melts at 112.8 °C (235 °F). 10.1 Compounds Containing Sulfur Thiols and Disulfides. When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound. Sulfide definition is - any of various organic compounds characterized by a sulfur atom attached to two carbon atoms. Beyond that temperature, the chains break down into small fragments. It is stable at temperatures below 96 °C (204.8 °F). Well by definition, if something is found in the periodic table its an element, if its not it is not an element!! The name itself probably found its way into Latin from the language of the Oscans, an ancient people who inhabited the region including Vesuvius, where sulfur deposits are widespread. An orthorhombic modification, S12 ring molecules, and still another unstable S10 ring allotrope are reported. A decrease in viscosity as temperature increases is typical of liquids, but the increase in the viscosity of sulfur above 157 °C probably is caused by rupturing of the eight-membered rings of sulfur atoms to form reactive S8 units that join together in long chains containing many thousands of atoms. The use of sulfur in explosives and fire displays dates to about 500 bce in China, and flame-producing agents used in warfare (Greek fire) were prepared with sulfur in the Middle Ages.
