Chemistry

ScanSolve AI Answer

Step-by-step solution

2 steps
  1. Define metalloids.

    Metalloids are a group of chemical elements that exhibit properties intermediate between those of metals and non-metals. They are typically semiconductors, meaning they can conduct electricity under certain conditions but not as well as metals.

  2. Evaluate the given options based on the definition of metalloids.

    • A. have properties of metals only. This statement is incorrect. Elements with properties of metals only are classified as metals.
    • B. have properties of non-metals only. This statement is incorrect. Elements with properties of non-metals only are classified as non-metals.
    • C. have properties of metals and non-metals. This statement is correct. Metalloids possess a combination of metallic and non-metallic properties. For example, they may look like metals but behave chemically more like non-metals, or they might be semiconductors.
    • D. do not have properties of both metals and non-metals. This statement is incorrect. It contradicts the definition of metalloids.

    The final answer is C\boxed{\text{C}}.
