Which Elements Are Metalloids?
Metalloids, also known as semimetals, are elements that exhibit properties intermediate between those of metals and nonmetals. They typically appear metallic but do not conduct electricity as efficiently as metals, making them useful as semiconductors. The commonly recognized metalloids include:
- Boron (B)
- Silicon (Si)
- Germanium (Ge)
- Arsenic (As)
- Antimony (Sb)
- Tellurium (Te)
- Polonium (Po)
Some sources also suggest that elements like selenium and astatine may sometimes be classified as metalloids, though this classification can vary. Metalloids are often found along the “staircase” line on the periodic table, which separates the metals from the nonmetals. They are known for their brittle nature and semi-conductive properties, which are crucial in various technological applications such as electronics and optics.
Metalloids
Metalloids are the elements in the Chemistry Periodic Table whose properties lie in between those of metals and non-metals. All the elements in the periodic table are classified into three categories namely Metals, Non-Metals, and Metalloids. Elements in the periodic table(an arrangement of different elements in order of their increasing atomic number) for the study of their properties, nature, and reaction with other elements.
