Explain about Non-metals.
Answers
Non-metals are natural materials that do not produce heat or electricity and that are structurally brittle (can not be easily rolling, moulding, extruding or pressing). Chemically, hydrogen, carbon, nitrogen, oxygen, phosphorus, arsenic, and selenium are the non-metallic elements in the periodic table.
Seventeen elements are generally classified as nonmetals; most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).
Answer:
Nonmetal or non-metal is a chemical element that does not have the properties of a metal. Some are gases including: hydrogen, helium, oxygen, nitrogen, fluorine, neon or radon and many others. ... A non metal is also a good insulator for heat and cold. Usually, gases or brittle solids are non-metals
