Which statement best describes metals, metalloids, and non-metals?

• A. Metals Conduct Electricity and Are Ductile; Metalloids Are Semiconductors; Non-Metals Are Poor Conductors
• B. Metals Conduct Electricity and Are Brittle; Metalloids Are Insulators; Non-Metals Are Shiny
• C. Metals Conduct Electricity Only When Molten; Metalloids Are Non-Conductive; Non-Metals Are Tough
• D. Metals Conduct Electricity and Are Ductile; Metalloids Are Semiconductors; Non-Metals Are Poor Conductors

Answer: (D)

Understanding how metals, metalloids, and non-metals behave in terms of electricity and shape helps make sense of this statement. Metals typically let electric current flow easily and are malleable and ductile, meaning they can be drawn into wires and hammered into sheets. Metalloids sit between metals and non-metals and often act as semiconductors, so their ability to conduct electricity can be controlled by conditions or impurities. Non-metals generally do not conduct electricity well and are not ductile; many are brittle and can be solids, liquids, or gases at room temperature. So, describing metals as good conductors that are ductile, metalloids as semiconductors, and non-metals as poor conductors captures the common, useful distinctions used in science. Some exceptions exist, but this framework matches everyday patterns the question targets.
