Answer :
Final answer:
Metalloids, like silicon and germanium, have unique characteristics of both metals and nonmetals. They are most notably known as semiconductors, able to conduct electricity under certain conditions.
Explanation:
Metalloids are elements on the periodic table that lie between metals and nonmetals. These elements, such as silicon and germanium, have properties of both metals and nonmetals. Their most prominant characteristic is their ability to function as semiconductors. Unlike metals, which are good conductors, or nonmetals, which are generally poor conductors, metalloids can carry an electrical charge under the right conditions. Thus, the correct answer to your question would be option C: metalloids are semiconductors.
