Metals, Nonmetals, and Metalloids

Front

What is a metal?

Back

A metal is a type of element that is typically shiny, malleable, ductile, and a good conductor of heat and electricity.

Front

What is a nonmetal?

Back

A nonmetal is an element that is usually dull, brittle, and a poor conductor of heat and electricity.

Front

What is a metalloid?

Back

A metalloid is an element that has properties of both metals and nonmetals, often used in semiconductors.

Front

What property of metals makes them malleable?

Back

Metals can be hammered or rolled into thin sheets without breaking due to their atomic structure.

Front

What is conductivity?

Back

Conductivity is the ability of a material to conduct electricity or heat.

Front

Give an example of a metal and its use.

Back

Example: Copper is a metal used in electrical wiring due to its excellent conductivity.

Front

What is the significance of silicon in technology?

Back

Silicon is a metalloid used in making semiconductors, essential for electronic devices.

Front

What are the common properties of nonmetals?

Back

Nonmetals are generally poor conductors of electricity and heat, and they are not malleable or ductile.

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows electricity to flow easily, while an insulator resists the flow of electricity.

Front

What is an example of a nonmetal?

Back

Example: Oxygen is a nonmetal essential for respiration.
