Metals, Nonmetals, Metalloids

Front

What is a metalloid?

Back

A metalloid is an element that has properties of both metals and nonmetals. Examples include silicon and germanium.

Front

Which elements are typically malleable?

Back

Metals are typically malleable, meaning they can be hammered or rolled into thin sheets.

Front

What is a key property of metals?

Back

Metals are good conductors of electricity and heat.

Front

What is a characteristic of nonmetals?

Back

Nonmetals are often brittle when solid and are poor conductors of heat and electricity.

Front

What is a semiconductor?

Back

A semiconductor is a material that has conductivity between that of a conductor and an insulator, often made from metalloids.

Front

Give an example of a nonmetal.

Back

An example of a nonmetal is oxygen.

Front

What is the state of most metals at room temperature?

Back

Most metals are solid at room temperature, except for mercury, which is a liquid.

Front

What is the appearance of nonmetals?

Back

Nonmetals can be dull in appearance and are not shiny like metals.

Front

What is the term for elements that can conduct electricity under certain conditions?

Back

The term is 'semiconductors', which are typically metalloids.

Front

What is the difference between metals and nonmetals in terms of conductivity?

Back

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