Which of the following is a typical physical property of metals?

• A. They have low melting points.
• B. They are usually brittle.
• C. They are good conductors of electricity.
• D. They are generally dull in appearance.

Answer: (C)

Verified step by step guidance

1. Understand what physical properties are: Physical properties are characteristics of a substance that can be observed or measured without changing the substance's chemical identity.
2. Recall typical physical properties of metals: Metals generally have high melting points, are malleable (not brittle), have a shiny (lustrous) appearance, and are good conductors of electricity and heat.
3. Evaluate each option against these known properties: Low melting points and brittleness are not typical of metals; metals usually have high melting points and are malleable rather than brittle.
4. Recognize that being good conductors of electricity is a hallmark physical property of metals due to the presence of free-moving electrons.
5. Conclude that the correct typical physical property of metals from the given options is that they are good conductors of electricity.
