Metalloid Guide, Meaning , Facts, Information and Description

Together with the metals and nonmetals, the metalloids (or semimetals) form one of the three categories of chemical elements as classified by ionization and bonding properties. They have properties intermediate between those of metals and nonmetals. There is no unique way of distinguishing a metalloid from a true metal but the most common is that metalloids are usually semiconductors rather than conductorss.

The known metalloids are:

• boron (B)
• silicon (Si)
• germanium (Ge)
• arsenic (As)
• antimony (Sb)
• tellurium (Te)
• polonium (Po)

New elements that should be metalloids

• ununhexium (Uuh)
• ununseptium (Uus) (117; not yet synthesized)

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.
