sulfur

 chemical properties:
 * Name:** Hoai Tran
 * Title name's:** all about the elements
 * Element name**: Sulfur :Sulfur is a multivalued non-metal, abundant, tasteless and and odorless. In its native form sulfur a yellow crystalline solid. In nature it occurs as the pure element or as sulfide and sulfate minerals. Although sulfur is infamous for its smell, frequently compare to rotten eggs, that odor is actually characteristic of hydrogen sulphide (H2S).
 * Symbol**: S
 * Atomic number**:16
 * Atomic mass**: 32.06
 * Number of proton**:16
 * Number of electron**: 16
 * Number of neutron**: 16
 * Common** **Isotopes**:
 * Electron configuration**:1s2 2s2 2p6 3s2 3p4
 * Physical properties:**Sulfur dioxide reacts with a soda lime mixture. As the gas is consumed, a rubber dam covering the top of the beaker is pushed inward by atmospheric pressure.
 * Color is a strong yellow color in thick crystals and duller yellow in small crystals to pale yellow in massive or powdery forms. Can also be reddish or greenish yellow with impurities.
 * Transparency is transparent to translucent.
 * **Sulfur can be found:**Sulfur can be found in the air in many different forms. It can cause irritations of the eyes and the throat with animals, when the uptake takes place through inhalation of sulfur in the gaseous phase.
 * Elemental sulfur can be found near hot spring and volcanic regions in many parts of the world,
 * Health effects of sulfur**:All living things need sulfur. It is especially important for humans because it is part of the amino acid methionine, which is an absolute dietary requirement for us.
 * Uses use in medical** :Sulfur products have antibacterial, peeling and drying actions. This medication is used on the skin to treat mild acne and oily skin.
 * Sulfur(**S**) has 25 isotopes, four of which are stable: 32S (95.02%), 33S (0.75%), 34S (4.21%), and 36S (0.02%). Other than 35S, the radioactive isotopes of sulfur are all short lived. 35S is formed from cosmic ray spallation of 40Ar in the atmosphere . It has a half-life of 87 days. Standard atomic mass: 32.065(5)
