Question

which property do metalloids share with nonmetals?
○ both are brittle.
○ both are shiny.
○ both have low melting points.
○ both are very conductive.

Explanation:

Metalloids are elements that have properties of both metals and non - metals. Non - metals are generally brittle (they break easily when force is applied). Metalloids also have the property of being brittle. Metals are shiny (lustrous), non - metals are usually not shiny and metalloids can have a metallic - like appearance but this is not a property they share with non - metals. Non - metals can have a wide range of melting points (e.g., carbon has a very high melting point), and metalloids also have varying melting points, so low melting point is not a common property. Non - metals are poor conductors (except for some like graphite), and metalloids are semiconductors (not very conductive like metals).

Answer:

Both are brittle.
