Information AboutMetalloid |
|
The known metalloids (and their Atomic Symbols ) are:
In the Periodic Table , metalloids occur along the diagonal line from boron to polonium. Elements to the upper right of this line are nonmetals; elements to the lower left are metals. Semi-metallic behaviour is not confined to the elements, but is also found in Alloys and Compounds . Mercury (II) Telluride is one example. One definition of semi-metallic behavior would be if the Conduction Band and Valence Band overlap. This is also true of metals, so semi-metals must additionally have a relatively low carrier density. |
