Answer:
Examples: Si, B, Ge, Sb, Ga
Explanation:
The majority of elements in the periodic table are classified as either a metal (a species that can lose electrons to become a cation) or a non-metal (a species that can gain electrons to become an anion).
However, there are several atoms which are considered to be metalloids. Metalloids are elements which possess properties that resemble both metals and non-metals. Examples of metalloids would be: silicon (Si), boron (B), germanium (Ge), antimony (Sb), gallium (Ga).
Since metalloids have properties of both metals and non-metals, they are widely used in semiconductors, as they might both donate and accept electrons in their shells.
