Sulfur element

Sulfur is a very active element, which can be removed with inert gas Elements other than iodine and molecular nitrogen can easily react with sulfur directly or share two electrons with other elements to form compounds with oxidation states of - 2,+6,+4,+2,+1- 2-valent sulfur has stronger Reducibility (The reducibility is determined by the ability to obtain electrons), sulfur usually only metallic element Reduction to a weaker valence state (e.g., reduction of Fe to 2 -, and reduction of Cu to 1 -). The main sulfur variants are orthorhombic sulfur and monoclinic sulfur. Their melting points are 112.8 ° C respectively（ Orthorhombic sulfur ）And 119 ° C（ Monoclinic sulfur ）, boiling point 444.674 ° C, density 2.07 g/cm3 (orthogonal sulfur) and 1.96 g/cm3 (monoclinic sulfur). Solid sulfur has a variety of crystal forms, and orthogonal sulfur is a stable form of sulfur at room temperature.
