Description The term "metal" designates an element which is good
conductor of electricity and whose electric resistance is directly
proportional to the absolute temperature (Wittmann, 1979). In
addition to this distinctive characteristic, metals share several
other typical physical properties such as high thermal conductivity,
high density, malleability and ductility. Several non-metallic
elements exhibit one or more of these properties, so that the only
feature that defines a metal unambiguously is the electric
conductivity which decreases with increasing temperature.
Within a given period the properties of the elements vary
gradually from a high electropositive (metallic) character at the
left-hand side of the series to the highly electronegative (nonmetallic)
character at the end of the series. The "metalloids" (or
half metals) such as boron, silicon, germanium, arsenic and
tellurium are balanced in the Periodic Table between metals and
non-metals
