Properties of the P.T.

Front

What is luster?

Back

Luster is the ability of a material to reflect light, making it appear shiny. It is a characteristic property of metals.

Front

What are conductors?

Back

Conductors are materials that allow electricity and heat to flow through them easily. Metals are the best examples of conductors.

Front

What are nonmetals?

Back

Nonmetals are elements that do not conduct electricity or heat well. They are typically dull and brittle.

Front

What is a semiconductor?

Back

A semiconductor is a material that allows some flow of heat and electricity. Metalloids are examples of semiconductors.

Front

Which group of elements is known for high conductivity?

Back

Metals are known for their high conductivity of electricity and heat.

Front

What is the primary characteristic of metalloids?

Back

Metalloids have properties that are intermediate between metals and nonmetals, including semiconducting abilities.

Front

Give an example of a metal and its property.

Back

Example: Copper; it is a metal known for its excellent electrical conductivity.

Front

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

Back

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

Front

What is the appearance of metals?

Back

Metals typically have a shiny appearance due to their luster.

Front

Name a property of nonmetals.

Back

Nonmetals are generally brittle and do not have a metallic luster.
