what r metals and non metals
Answers
Metals: Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire). Most of the metals are solids at room temperature, with a characteristic silvery shine (except for mercury, which is a liquid). A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable or ductile.
Non - metals: 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. In chemistry, a nonmetal is a chemical element that usually gains one or more electrons when reacting with a metal and forms an acid when combined with oxygen and hydrogen. At room temperature about half are gases, one is a liquid, and the rest are solids.
