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, principally in the form of troilite (FeS), comprising around 1% of the lunar crust. Magnetic benefication may be able to concentrate troilite out of the lunar regolith, as it is weakly magnetic when the crystal structure is incomplete, as well as being commonly associated with native iron. In addition, concentrated veins of troilite have been found in some lunar rocks, and it has been suggested that larger deposits of the mineral may exist.
