Which property do metalloids share with nonmetals?

• A. They have high malleability.
• B. They tend to form basic oxides.
• C. They are generally poor conductors of electricity.
• D. They are typically shiny and lustrous.

Answer: (C)

Verified step by step guidance

1. Understand the nature of metalloids: Metalloids have properties intermediate between metals and nonmetals.
2. Recall that metals are typically good conductors of electricity, malleable, and lustrous, while nonmetals are generally poor conductors and not malleable.
3. Identify that metalloids often share the property of poor electrical conductivity with nonmetals, although some metalloids can conduct electricity under certain conditions (semiconductors).
4. Recognize that malleability and lustrous appearance are characteristic of metals, not metalloids or nonmetals.
5. Conclude that the property metalloids share with nonmetals is that they are generally poor conductors of electricity.
