Transcript of Sulfur

16 16 Sulfur S 32.065 16 Protons 16 Electrons 16 Neutrons The name sulfur came from the arabic word 'sufra' meaning yellow. Another name for sulfur which was used first is brimstone. Sulfur has been known since ancient times. Sulfur became recognized as an element in 1777 when Antoine Lavoisier convinced the other scientists that it was an element by including it in his famous list of the element. History 16 Sulfur is found in meteorites, volcanoes, hot springs, other planets, and minerals such as galena, gypsum, Epsom salts, and barite. Most sulfur is obtained from underground deposits like salt deposits. Sulfur Dioxide SO 2 Sulfur dioxide is formed by burning sulfur in air. It is covalent. When water is added to sulfur dioxide it turns to acid rain. Sulfur dioxide can be used as a preservative for dried fruits like apricots or figs. It maintains the colorful appearance of the fruit and makes sure it doesn't rot. Also used in wines. It protects wine from spoiling by bacteria. In the presence of water, sulfur dioxide is able to decolorize substances. It is useful to use on clothes. The only problem is, it normally does not last very long. Sulfur dioxide is a noticeable component in the atmosphere, especially following volcanic eruptions. Since sulfur dioxide blocks sunlight it puts harm to plants and animals. Inhaling sulfur dioxide is associated with increased respiratory symptoms and disease, difficulty in breathing, and premature death. Sulfur in Daily Use Used in black gunpowder, matches, and fireworks. Also used in the vulcanization of rubber; which is when you add sulfur to rubber changing it into a more durable material. Oxygen VS Sulfur Similarities Both form ionic compounds with active metals. Both in the Chalcogen group. Both form similar covalent compounds e.g. H2O and H2S, CO2 and CS2. Differences Oxygen is a lot smaller than sulfur. Sulfur is a solid at room temperature but oxygen is a gas at room temperature. Both nonmetals. More sulfur is located on other planets than oxygen. Oxygen About one fifth of the atmosphere is oxygen gas. About two thirds of the human body, and nine tenths of water, is oxygen. Oxygen has 8 neutrons, electrons, and protons. Atomic number is 8 and atomic mass is 16. Oxygen is a nonmetal and a gas at room temperature. Sulfur Hexafluoride Works Cited
