Research Paper On Sulfur

Sulfur Sulfur symbol is “S”. Sulfur was discovered in 1777. It’s been known since ancient times. A nonmetal, sulfur is the 10th most abundant element in the universe. Sulfur makes up almost 3 percent of the Earth's mass. This bright yellow element, known in the Bible as "brimstone," is abundant in nature, and was used for a variety of purposes in ancient times. Pure sulfur has no smell. The stink associated with the element comes from many of its compounds. Sulfur atomic number is sixteen. Its atomic number is 32.066. Sulfur has 4 stable Isotopes. It’s is located in period three, group sixteen. Sulfur is in the Oxygen family. Its family members are oxygen, selenium, tellurium and polonium. The first four are nonmetals and are called the chalcogens. In this group only sulfur has a strong tendency of catenation. Oxygen also shows this tendency to some extent. All these elements belong to p-block elements. Polonium has metallic character and it is a radioactive material with very short period.

It’s color is yellow and is Non- Metallic. Sulfur is solid at room temperature. Its melting point is 239.4°F and its boiling point is 832.4°F. Sulfur can sublimate between temperature 25 degree Celsius and 50 degree Celsius. In nature Sulfur is found as an mineral in hot springs and in volcanic region. Sulfur makes up almost 3 percent of the Earth's mass. The average cost for sulfur is two dollars per gram. Burning Sulfur produces sulfur dioxide gas, emitting a blue flame in the process. Sulfur dioxide is noted for its pungent suffocating odor. Sulfur is insoluble in water, but soluble in carbon disulfide, somewhat soluble in other non-polar organic solvents such as the aromatics benzene and toluene. An atom having such an electronic structure tends to form a stable shell of eight electrons by adding two more, producing an ion that has a double negative charge. This means that group sixteen is highly
