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 metalloids used for?
Three uses of a metalloid is semiconductors, some cleaning materials, and computer chips
No. All metalloids are solid at room temperature.
Metalloids (or semiconductors) are important components of electronic devices. Metalloids have other uses as well. For example, antimony is used in alloys such as pewter and as a flame retardant in plastics. Boron is used as a bonding agent in magnets and other chemical substances.
Metalloids have characteristics of both metals and non-metals. They are located on the staircase of the periodic table. Some examples of metalloids are boron, silicon, arsenic, etc.

Metalloids are elements that have properties of both metals and nonmetals. They are often used as semiconductors meaning they can be used to conduct electricity under certain conditions. The major uses of metalloids include: Electronics Metalloids are used in transistors and diodes which are essential components of almost all electronic devices. Solar Cells Metalloids such as silicon are used in solar cells to capture and convert solar energy into electricity. Aerospace Metalloids are used in the aerospace industry for various purposes including wiring and fuel systems. Medicine Metalloids can be used to create medical implants and prosthetics as well as drug delivery systems. Industrial Metalloids are used in the production of various industrial products such as steel aluminum and other alloys.Metalloids are also used in the production of optical lenses and as a catalyst in chemical reactions. These elements are essential to many industries and have numerous uses in modern society.

Three uses of metalloids are something and if you find the right answer please tell me i need to know ~ the person who needs to know
Compounds of boron are used in some cleaning materials. A compound of boron and oxygen is added during the process of making glass to make heat-resistant glass. Silicon combines with oxygen to from silicon dioxide. - Satchi <3 Metalloids have several uses and applications. Three examples include uses within pressure industries, science research, and as semiconductors.
True. Metalloids look like metals but are brittle and are not good conductors.
Elements that have some characteristics of a metal and some characteristics of a nonmetal are called semimetals or metalloids.
