Together with the metals and nonmetals, the metalloids (in Greek metallon = metal and eidos = sort - also called 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 conductors.
The known metalloids (and their atomic symbols) are:
Boron (B)
Silicon (Si)
Germanium (Ge)
Arsenic (As)
Antimony (Sb)
Tellurium (Te)
Polonium (Po)
Astatine (At)
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.

What are the two metalloids in the nitrogen family?
The two metalloids in the nitrogen family are arsenic and antimony.
Which two elements along the stair are not metalloids?
The two elements along the stair that are not metalloids are aluminum and polonium. Aluminum is a metal, while polonium is a metal.
What is unique about metalloids?
Metalloids are a 'one-of-a-kind' element. They contain a mix of chemical and physical properties from both metals and nonmetals. Metalloids can act as either a metal or a nonmetal, which makes them a metalloid.
How many metalloids are in the carbon family?
there are two elements. those are tin and lead. Tin and lead are NOT metalloids. The two metalloids in group 14 (same group as Carbon) would be silicon (Si) and germanium (Ge).
Are all metalloids man made?
No, metalloids are not all man-made. Metalloids are a group of elements on the periodic table that have properties of both metals and nonmetals. Some metalloids, like boron and silicon, are naturally occurring elements.
