WebSulfur ion lewis dot structure. Sulfur is a ‘Group 16’ element. It has six electrons in outer most shell 3s and 3p. From Octet rule we know that every element covers its outer most shell with eight electrons. This makes the element more stable. So Sulfur needs two more electrons for the stability like nearest Noble gas. Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room … Meer weergeven Physical properties Sulfur forms several polyatomic molecules. The best-known allotrope is octasulfur, cyclo-S8.
