What are examples of mateloids?

Metalloids are elements that exhibit properties intermediate between metals and nonmetals. Common examples include silicon (Si), which is widely used in electronics and semiconductors; germanium (Ge), often used in fiber optics and transistors; and arsenic (As), which has applications in various alloys and pesticides. Other examples include boron (B), antimony (Sb), and tellurium (Te). These elements typically have varying degrees of electrical conductivity and can form alloys and compounds with both metals and nonmetals.
