Final answer:
Metalloids are the elements that have properties of both metals and nonmetals. They are found along the staircase on the periodic table and include elements such as boron, silicon, germanium, arsenic, antimony, and tellurium.
Step-by-step explanation:
Metalloids are the elements that have properties of both metals and nonmetals. They are found along the staircase on the periodic table and include elements such as boron, silicon, germanium, arsenic, antimony, and tellurium.
Unlike metals, metalloids are not good conductors of electricity. However, they can conduct electricity under certain conditions. Metalloids also exhibit properties of nonmetals, such as brittleness and low melting points.
For example, silicon is a metalloid that is used in computer chips and solar cells. It has some metallic properties, like being a good conductor of electricity, but also some nonmetallic properties, like being brittle.
