The correct statement about metals and nonmetals is: Metals can be hammered into thin sheets, and nonmetals are brittle.
- Metals are malleable, meaning they can be hammered or rolled into thin sheets.
- Nonmetals are typically more brittle in their solid form and do not have the same malleability as metals.
The other statements are incorrect. For example, metals are generally good conductors of electricity, while nonmetals are usually poor conductors, and most metals are solid under normal conditions, with only a few exceptions like mercury. Additionally, metals and nonmetals are found in different regions of the periodic table, with metals on the left and nonmetals on the right.
