metals and nonmetals

Front

What are metals?

Back

Metals are elements that are generally shiny, malleable, ductile, and good conductors of heat and electricity.

Front

What are nonmetals?

Back

Nonmetals are elements that are generally dull, brittle, and poor conductors of heat and electricity.

Front

Name three examples of metals.

Back

Iron (Fe), Copper (Cu), and Aluminum (Al).

Front

Name three examples of nonmetals.

Back

Oxygen (O), Carbon (C), and Sulfur (S).

Front

What property of metals makes them good for electrical wiring?

Back

Metals are good conductors of electricity due to their free-moving electrons.

Front

Why are nonmetals used as insulators?

Back

Nonmetals are poor conductors of electricity and heat, making them good insulators.

Front

Which property allows metals to be hammered into thin sheets?

Back

Malleability

Front

Which property allows metals to be drawn into wires?

Back

Ductility

Front

What type of bond is found in metals?

Back

Metallic bonds, where electrons are delocalized in a "sea of electrons."

Front

How do the physical states of metals and nonmetals differ at room temperature?

Back

Most metals are solid, while nonmetals can be solid, liquid, or gas at room temperature.
