(1) The first is the ÔÇÿbulkÔÇÖ elements, which include calcium, phosphorus, sulfur , potassium, chlorine, sodium, and magnesium.(2) Aluminum was named for one of its most important compounds, alum, a compound of potassium, aluminum, sulfur and oxygen.(3) Oxygen is a particularly strong embrittling agent for molybdenum and tungsten; nitrogen and sulfur are particularly harmful in wrought chromium.(4) Stainless steel is an alloy composed of various percentages of iron, nickel, sulfur , carbon, silicon, manganese, and chromium.(5) Boron, silicon, nitrogen, phosphorus and sulfur are among the most prevalent of the elements other than carbon that form covalent compounds.(6) Potassium also reacts readily with all acids and with many nonmetals, such as sulfur , fluorine, chlorine, phosphorus, and nitrogen.(7) Because iron has an affinity electronegative atoms such as oxygen, nitrogen and sulfur , these atoms are found at the heart of the iron-binding centers of macromolecules.(8) Other elements added to improve characteristics include nickel, molybdenum, copper, titanium, aluminum, silicon, niobium, nitrogen, sulfur , and selenium.(9) The sulfur butterflies, Colias philodice and C. eurytheme, are economic pests of alfalfa and clover crops.(10) It combines easily with many non-metals, including nitrogen, sulfur , phosphorus, and the halogens.(11) What they have in common are ball-like clusters of flowers of a bright sulfur yellow that fades to a softer orange-yellow as the seeds form.(12) Acid rain results when sulfur and nitrogen compounds - products of fossil fuel combustion - rise into the atmosphere and combine with water.(13) These include iron, calcium, sulfur , manganese, molybdenum, zinc, boron, and copper.(14) Neither the white-dwarf theory nor the the black-hole theory can explain the presence of sulfur (ÔÇÿbrimstoneÔÇÖ) in the lake of fire, if it is to be taken literally.(15) Coal is a solid organic material made up of large, complex molecules containing mostly carbon, plus small amounts of hydrogen, sulfur , nitrogen and oxygen.(16) Most of your mass is carbon, oxygen, hydrogen, sulfur , plus some nitrogen and phosphorous.
