Reactions of elemental fluorine with metals require varying conditions. The sulfur is oxidized to produce granules of elemental sulfur. Physical abilities use up HP whilst elemental and support magic use SP. Most sulfur dioxide is produced by the combustion of elemental sulfur. SCl hydrolyzes to sulfur dioxide and elemental sulfur. The main use of hydrogen sulfide is as a precursor to elemental sulfur. Like other iodide salts, forms when combined with elemental iodine. It thermally decomposes into disulfide and elemental sulfur. Triphenylphosphine abstracts sulfur from polysulfide compounds, episulfides, and elemental sulfur. Boron does not appear on Earth in elemental form. Boron trichloride is a starting material for the production of elemental boron. Rituals were therefore centered around the worship of those elemental deities. Electron microscopes can be coupled to spectroscopic methods that can perform elemental analysis. Different studies generally find varying values for elemental abundances. Pure germanium is a semiconductor with an appearance similar to elemental silicon.
