Which term describes an element that has properties of both metals and nonmetals?

• A. Metalloid
• B. Metal
• C. Nonmetal
• D. Alloy

Answer: (A)

Metalloids are elements that exhibit properties of both metals and nonmetals. They often look shiny like metals but tend to be brittle and have electrical conductivity that sits between metals and nonmetals. This intermediate behavior, especially their semi-conductive nature, makes them crucial in electronics, with silicon and germanium as classic examples used in computer chips. Metals are typically good conductors and malleable, nonmetals are usually poor conductors and not malleable, and alloys are mixtures of elements, not single elements. So the term that best describes an element with mixed metal and nonmetal properties is metalloid.
