* Boron (B)
* Silicon (Si)
* Germanium (Ge)
* Arsenic (As)
* Antimony (Sb)
* Tellurium (Te)
* Polonium (Po)
Note: While polonium is sometimes classified as a metalloid, it's more commonly considered a metal due to its properties.
Metalloids are fascinating because they exhibit characteristics of both metals and nonmetals. This makes them crucial in various applications, such as:
* Semiconductors: Silicon and germanium are the foundation of modern electronics.
* Doping agents: Arsenic and antimony are used to enhance the conductivity of semiconductors.
* Alloys: Boron and silicon are used to improve the strength and properties of metals.
* Fire retardants: Antimony and tellurium are used in fire retardants and other safety applications.
