GENERAL KNOWLEDGE

Detailed explanation-1: -Silicon is classified as a metalloid since some of its properties are similar to those of metals and some of its properties are similar to those of nonmetals.

Detailed explanation-2: -Silicon is neither metal nor non-metal; it’s a metalloid, an element that falls somewhere between the two. The category of metalloid is something of a gray area, with no firm definition of what fits the bill, but metalloids generally have properties of both metals and non-metals.

Detailed explanation-3: -Silicon has properties in between those of metals and non-metals. Thus, it is a metalloid.

Detailed explanation-4: -The elements which are found in the step-like line between metals and nonmetals of the periodic table are known as the metalloids. They are: antimony (Sb), germanium (Ge), silicon (Si), arsenic (As), tellurium (Te), polonium (Po), boron (B), and astatine (At).

Detailed explanation-5: -Survey of Elements Commonly Recognized as Metalloids The percentage appearance frequencies of the elements most frequently identified as metalloids are boron (86), silicon (95), germanium (96), arsenic (100), selenium (23), antimony (88), tellurium (98), polonium (49), and astatine (40).
