Science / Periodic Table of Elements / Nonmetal: A nonmetal is a substance that conducts heat and electricity poorly, is brittle or waxy or gaseous, and cannot be hammered into sheets or drawn into wire. Nonmetals gain electrons easily to form anions. About 20% of the known chemical elements are nonmetals.
Business / Machine Shop / Phosphorous: A highly reactive, toxic, nonmetallic element used in steel, glass and pyrotechnics. It is almost always found in combination with other elements such as minerals or metal ores. Found in steel and cas MORE
