Which properties do metalloids share with metals? both are shiny and are brittle. both are very conductive and are dull. both are brittle and are gases at room temperature. both are shiny and are solid at room temperature.

the correct answer is:

both are shiny and are solid at room temperature.

explanation:

metalloids exist between metals and nonmetals. metalloids are solely solid at room temperature. they can set alloys with other metals.

typical metalloids have a metallic character, but they are brittle and only fair conductors of electricity.

while metals are : bright (shiny) .hard.high frequency (are heavy for their size).high tensile strength (resist being stretched).high melting and boiling points.

its going to be mutualism cuz they both benefit from the relationship.
