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 non-metals?

Back

Non-metals are elements that are usually dull, poor conductors of heat and electricity, and brittle in solid form. Examples include sulfur, oxygen, and carbon.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and non-metals. They can be semiconductors and are often used in electronics. Examples include silicon and arsenic.

Front

What is luster?

Back

Luster is the way light interacts with the surface of a mineral or element, giving it a shiny appearance. Metals and metalloids often exhibit luster.

Front

What does malleable mean?

Back

Malleable refers to the ability of a material, especially metals, to be hammered or pressed into thin sheets without breaking.

Front

What does brittle mean?

Back

Brittle describes a material that breaks or shatters easily when force is applied, commonly associated with non-metals.

Front

What is conductivity?

Back

Conductivity is the ability of a material to conduct electricity or heat. Metals are generally good conductors, while non-metals are not.

Front

What is the property of ductility?

Back

Ductility is the ability of a material to be stretched into a wire without breaking, a property commonly found in metals.

Front

What is the difference between metals and non-metals?

Back

Metals are typically shiny, conductive, malleable, and ductile, while non-metals are dull, brittle, and poor conductors.

Front

What is an example of a metalloid?

Back

Silicon is an example of a metalloid, known for its semiconductor properties and used in electronic devices.
