Which statement best describes the properties of metalloids on the periodic table?

• A. Metalloids have only nonmetallic properties.
• B. Metalloids have only metallic properties.
• C. Metalloids do not share any properties with metals or nonmetals.
• D. Metalloids exhibit properties of both metals and nonmetals.

Answer: (D)

Verified step by step guidance

1. Understand that metalloids are elements found along the zig-zag line (stair-step line) on the periodic table that separates metals and nonmetals.
2. Recall that metals typically have properties such as good electrical conductivity, malleability, and luster, while nonmetals tend to be poor conductors and are more brittle or gaseous.
3. Recognize that metalloids exhibit a combination of these properties, meaning they can behave like metals in some situations and like nonmetals in others.
4. Analyze the given statements and identify that metalloids cannot have only metallic or only nonmetallic properties because they share characteristics of both groups.
5. Conclude that the best description is that metalloids exhibit properties of both metals and nonmetals, reflecting their intermediate position on the periodic table.
