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 and non - metals can both be brittle. Non - metals are typically brittle solids (except for gases). Many metalloids also have a brittle nature. Metals are usually malleable and ductile, while metalloids and non - metals lack this property and can break easily. Shiny is more characteristic of metals. Low melting points are not a common shared property as some metalloids have relatively high melting points. High conductivity is a property of metals, and neither metalloids nor non - metals are very conductive (metalloids can be semiconductors in some cases but not highly conductive like metals).

Answer:

Both are brittle.
