Question

all of these properties describe metals except...
malleable
conductors
shiny
brittle

Explanation:

To solve this, we recall the properties of metals. Metals are typically malleable (can be hammered into shapes), good conductors of heat/electricity, and shiny (have metallic luster). Brittle materials break easily, and metals are not brittle (they are ductile/malleable instead). So the property that does not describe metals is brittle.

Answer:

brittle
