Sulfur is a Non-metal in group 16.
It has a Orthorhombic crystalline structure.
This element has 4 stable isotopes: 32, 33, 34, and 36.
Sulfur is availible in lunar soil in significant quantities, with some mare soils containing as much as .27% by weight, and can be obtained by roasting the soil at high temperatures. Several uses have been proposed for lunar sulfur, including rocket propellant, production of sulfuric acid for industrial processes, and the manufacture of sealants.
