Metals, Nonmetals, and Metalloids

Front

What is a metalloid?

Back

A metalloid is an element that has properties of both metals and nonmetals. They are often semiconductors of electricity.

Front

Which element is a metalloid?

Back

Polonium is an example of a metalloid.

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 a semiconductor?

Back

A semiconductor is a substance that can conduct electricity under certain conditions, typically associated with metalloids.

Front

What does brittle mean?

Back

Brittle describes a substance that breaks apart easily and is weak and fragile.

Front

What are metals known for?

Back

Metals are known for their good conductivity of heat and electricity, malleability, ductility, and shiny appearance.

Front

What is the difference between metals and nonmetals?

Back

Metals are good conductors of heat and electricity, while nonmetals are poor conductors.

Front

Give an example of a nonmetal.

Back

An example of a nonmetal is sulfur.

Front

What is ductility?

Back

Ductility is the ability of a substance to be stretched into a wire without breaking.

Front

What is malleability?

Back

Malleability is the ability of a substance to be hammered or pressed into thin sheets.
