A.

Most metals and nonmetals conduct electricity well, but metals cannot conduct heat.


B.

Most nonmetals can be drawn into a wire, while metals would break apart.


C.

Most metals and nonmetals conduct heat well, but nonmetals cannot conduct electricity.


D.

Most metals can be drawn into a wire, while nonmetals would break apart.

Answer 1

Answer:

D.   Most metals can be drawn into a wire, while nonmetals would break apart

Explanation:

The correct statement from the given choices is that most metals can be drawn into a wire while non-metals would break apart.

Metals are malleable due to the presence of metallic bonds between their atoms. The large electron cloud due to the electropositivity of metals allows for the wide range of physical properties observed in them.

• Metals are also conductors because they have free mobile electrons.
• Therefore they can conduct heat and electricity.

Non-metals are brittle and cannot conduct neither heat nor electricity.
