Metals, Non-Metals & Metalloids

Front

What are metals?

Back

Metals are elements that are typically shiny, good conductors of heat and electricity, malleable, and ductile. Examples include iron, copper, and gold.

Front

What are nonmetals?

Back

Nonmetals are elements that are usually dull, poor conductors of heat and electricity, and can be gases, liquids, or solids. Examples include oxygen, sulfur, and chlorine.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals. They are semiconductors of electricity. Examples include silicon and arsenic.

Front

What is conductivity?

Back

Conductivity is the ability of a material to conduct electricity. Metals have high conductivity, while nonmetals have low conductivity.

Front

Which group of elements has the highest conductivity?

Back

Metals have the highest conductivity among the three groups: metals, metalloids, and nonmetals.

Front

What is luster?

Back

Luster is the shine or glow of a surface. Metals and metalloids can exhibit luster.

Front

Give an example of a metal that is commonly used in electrical wiring.

Back

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

Front

What is the difference between a metal and a nonmetal in terms of physical properties?

Back

Metals are usually shiny, malleable, and good conductors, while nonmetals are dull, brittle, and poor conductors.
