The correct statement about metals and nonmetals is:
Metals are malleable, and nonmetals are not.
- Most metals are indeed solid at room temperature (with the exception of mercury) and are malleable and ductile.
- Most nonmetals are gases at room temperature, with some (like bromine) being liquid, but they are not primarily liquids.
- Metals are generally good conductors of electricity, while nonmetals are generally poor conductors.
- Metals and nonmetals do not occupy every column of the periodic table; for example, the left side and middle of the periodic table are mainly metals, whereas the right side consists of nonmetals.
