Final answer:
Metalloids have characteristics that are between metals and nonmetals, making them useful as semiconductors. Three examples of metalloids include Boron, Arsenic, and Antimony.
Step-by-step explanation:
Metalloids are elements that exhibit properties intermediate between those of metals and nonmetals. These properties make metalloids especially useful as semiconductors, which is vital in the electronics industry.
Metalloids typically have a metallic luster but are brittle, and they conduct heat and electricity better than nonmetals but not as well as metals. The ability to act as semiconductors arises due to their intermediate electrical conductivity.
Examples of Metalloids
Three notable examples of metalloid elements are:
- Boron (B)
- Arsenic (As)
- Antimony (Sb)
