write down the property of metal and nonmetal with definition
Answers
Explanation:
This depends on your definition of "metal", but in the general sense, a metal is comprised of atoms of an element that does not form specific chemical bonds between the atoms, but rather the atoms lie in a "sea" of loosely bound electrons. The major physical property is that accordingly, they conduct electricity, and also heat rather well. The sea of electrons also leads to the highest scattering of photons, so they appear extremely shiny if the surface is cleanly metallic. As they approach their melting point, provided the surface is clean, pieces can usually be joined together by pressure (e.g. hammering), and they usually form alloys with certain other metals (but not all). They usually react chemically with halogens to form salts that, if soluble in water, conduct electricity and give metallic cations, i.e., in electrolysis, the metal goes to the cathode.
Apart from that, there are not a lot of distinctive properties. You cannot say they are high melting (c.f. mercury and gallium) and sometimes the properties have exceptions. Thus sodium under extreme pressure goes transparent and presumably behaves more like a non-metal.
