Sulfer Dioxide Sulfer, Zwavel in Dutch, or Schwefel in German got its name from the latin word sulfur which means brimstone. It has 16 protons, neutrons, and electrons. The naturally occuring isotopes of sulfer are
32-S Abundence: 94.93 (31) Average atomic mass: 31.97207070 (25)
33-S Abundence: 0.76 (2) Average atomic mass: 32.97145843 (23)
34-S Abundence: 4.29 (28) Average atomic mass: 33.96786665 (22)
36-S Abundence: 0.02 (1) Average atomic mass: 35.96708062 (27)
There are three electron shells. Shell one has two, shell two has eight, and shell three has six. My atomic radius is 100 pm or picometers. Sulfer is odorless, tasteless, light yellow, and solid. It is a reactive element that under certain circumstances combines with all other elements except gases, gold, and platinum. Sulfer has a specific gravity of 2.07 (rhombic form) or 1.96 (monoclimic form). Sulfur dioxide, SO2, is a colorless gas with an irritating, choking odor. It is produced naturally in volcanoes and in geysers. No one really knows who discovered sulfur. Sulfur was known in ancient times and is referred to in Genesis in the Bible. English translations of the Bible refer to sulfur as brimstone. Sulfur was also known to the Chinese in the 6th century BC in its natural form. In the 3rd century the Chinese discovered how to isolate sulfur from the mineral pyrite, commonly known as fool’s gold. After isolation, the Chinese began using sulfur in medicine and sulfur has become a part of traditional Chinese medicine. Sulfer is used in some medicines. It is also used in some soaps, gunpowder ,used on matches, fertilizers ,fungicides, and pesticides. I obtaine most of my information from the website http://www.webelements.com/, the symbol for sulfur is S and the atomic mass number is 16.
