metals and nonmetals on the periodic table

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).  

Nonmetals are (usually) poor conductors of heat and electricity, and are not malleable or ductile; many of the elemental nonmetals are gases at room temperature, while others are liquids and others are solids.  

The metalloids are intermediate in their properties.  In their physical properties, they are more like the nonmetals, but under certain circumstances, several of them can be made to conduct electricity.  These semiconductors are extremely important in computers and other electronic devices.
