Question

element 4: copper
properties:

• reddish - brown, lustrous
• excellent conductor
• malleable & ductile
• solid at room temp

category:

Explanation:

To determine the category of copper, we analyze its properties: reddish - brown, lustrous appearance; excellent electrical and thermal conductivity; malleability, ductility; and solid state at room temperature. These are characteristic properties of metals. Metals are a category of elements in chemistry (a subfield of Natural Science) that typically exhibit metallic luster, good conductivity, malleability, ductility, and are solid at room temperature (except for mercury). Copper fits all these criteria, so it belongs to the category of metals.
