Which statements correctly compare metals and nonmetals?

• Metals tend to be good conductors of thermal energy. Nonmetals tend to be good insulators of thermal energy.

• Metals are dull and brittle. Nonmetals are shiny and malleable.

• Metals are good insulators of electricity. Nonmetals tend to be good conductors of electricity.

• Metals cannot be stretched into thin wires. Nonmetals can be stretched into thin wires.

Answer explanation

Statement F correctly highlights that metals are typically good conductors of heat and electricity, while nonmetals are not. This fundamental difference is key in comparing the two categories of elements.

Based on these properties, which element is most likely a nonmetal?

• Element 1

• Element 2

• Element 3

• Element 4

Answer explanation

Element 2 is most likely a nonmetal due to its properties, which typically include being poor conductors of heat and electricity, having lower melting and boiling points, and existing in various states at room temperature.

A student is trying to classify an unidentified, solid gray material as a metal or a nonmetal. Which question will best help the student classify the material?

• F Is the material malleable or ductile?

• G Does the material feel hard to the touch?

• H Will the material float in water?

• J Does the material feel rough or smooth?

Answer explanation

To classify the material, the best question is whether it conducts electricity. Metals typically conduct electricity well, while nonmetals do not. Therefore, asking about electrical conductivity will help determine its classification.

Which pair of elements are nonmetals and gases at room temperature and normal atmospheric pressure?

• Boron, B

• Aluminum, Al

• Fluorine, F

• Cesium, Cs

• Chlorine, Cl

Answer explanation

Fluorine (F) and Chlorine (Cl) are both nonmetals and exist as gases at room temperature and normal atmospheric pressure, making them the correct choices. The other options are either metals or not gases.
