The metals are a group of chemical elements that there present they all or great part of the following physical properties: solid state to normal temperature, exceptthe mercury that is liquid; opaqueness, except in very thin caps; good electrical and thermal drivers; brilliant, once polished, and crystalline solid-state structure.

METALS AND NO METALS

Areseparated in the periodic system by a diagonal line of elements. The elements to the left of this diagonal are the metals, and the elements to the right are not metals. The elements that integrate thisdiagonal - boron, silicon, germanium, arsenic, antimony, teluro, polonio and astato - they have properties both metallic and not metallic.

The most common metallic elements are the following ones:aluminium, barium, beryllium, bismuth, cadmium, calcium, cerium, chrome, cobalt, copper, gold, iridium, iron, lead, lithium, magnesium, manganese, mercury, molybdenum, nickel, osmium, palladium,platinum, potassium, radio, rodio, silver, sodium, tantalum, talio, torio, I tin, titanium, volframio, uranium, vanadium and zinc. The metallic elements can combine some with others and also with otherelements forming compounds, dissolutions and mixtures. A mixture of two or more metals or of a metal and certain not metals like the carbon it is named an alloy. The alloys of mercury with othermetallic elements are known as amalgams.

The metals show a wide margin in his physical properties. The majority of they are of greyish color, but some of them present different colors; the bismuth is...
