Metalloids, which are elements that have properties intermediate between metals and nonmetals, are primarily found in groups 13 to 16 of the periodic table. The most commonly recognized metalloids include boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te).
Specifically, boron is located in group 13; silicon and germanium are in group 14; arsenic and antimony are found in group 15; while tellurium is in group 16. These elements are often utilized in semiconductor technology, reflecting their unique electrical properties that differ from both metals and nonmetals.
