Which of the following is a property commonly associated with metals?

• A. They are generally brittle.
• B. They tend to form acidic oxides.
• C. They have low melting points.
• D. They are good conductors of electricity.

Answer: (D)

Verified step by step guidance

1. Understand the general properties of metals: Metals are typically characterized by their ability to conduct electricity and heat, malleability, ductility, and metallic luster.
2. Analyze the options given: 'They are generally brittle' is more characteristic of nonmetals or some metalloids, not metals, which are usually malleable rather than brittle.
3. Consider 'They tend to form acidic oxides': Metals usually form basic or amphoteric oxides, while nonmetals tend to form acidic oxides.
4. Evaluate 'They have low melting points': Most metals have relatively high melting points compared to nonmetals, so this is not a common property of metals.
5. Recognize that 'They are good conductors of electricity' is a hallmark property of metals due to the presence of free-moving electrons in their structure, making this the correct choice.
