Which property do metalloids share with nonmetals?

Question

Both are brittle.
Both are shiny.
Both have low melting points.
Both are very conductive.

Answer 1

Metalloids share the property of being "brittle" with nonmetals. While metalloids typically have some metallic properties (like being shiny and conductive), they can also exhibit nonmetal-like qualities, and one of those qualities is brittleness. Nonmetals are generally not malleable or ductile and tend to break or shatter when subjected to stress, similar to metalloids.
