Metalloids are elements that exhibit properties of both metals and nonmetals. On the Periodic Table, the most commonly recognized metalloids include boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and polonium (Po). These elements are typically found along the zig-zag line that separates metals and nonmetals. Their unique characteristics make them valuable in various applications, especially in semiconductors and electronics.
