Question

Answer the following question in 1-2 complete sentences.

Define metal. Identify the four primary types of metal.

Answer 1

A metal is an element (or alloy) that is typically lustrous, malleable, ductile, a good conductor of heat and electricity, and tends to form positive ions in chemical reactions. The four primary types are ferrous metals (contain iron, e.g., steel, cast iron), non‑ferrous metals (no iron, e.g., aluminum, copper), alloys (metal mixtures, e.g., brass, bronze) and precious/noble metals (corrosion‑resistant, high‑value metals such as gold, silver, and platinum).
