Metals, Non-Metals & Metalloids

Front

What is a metal?

Back

A metal is a shiny, malleable substance that conducts heat and electricity well. Examples include iron, copper, and aluminum.

Front

What is a non-metal?

Back

A non-metal is a substance that is usually dull, brittle, and does not conduct heat or electricity well. Examples include sulfur, oxygen, and carbon.

Front

What is a metalloid?

Back

A metalloid is an element that has properties of both metals and non-metals. They can conduct electricity and heat but are often brittle. Examples include silicon and arsenic.

Front

What property distinguishes metals from non-metals?

Back

Metals are generally good conductors of heat and electricity, while non-metals are poor conductors.

Front

What is the appearance of most metals?

Back

Most metals have a shiny, metallic luster.

Front

What is a common property of non-metals?

Back

Non-metals are often brittle and can break easily.

Front

Which element is classified as a metal: Manganese, Sulfur, Silicon, or Neon?

Back

Manganese is classified as a metal.

Front

What happens to non-metals when they are heated?

Back

Non-metals generally do not conduct heat well and may change state (e.g., from solid to gas) when heated.

Front

Can metalloids conduct electricity?

Back

Yes, metalloids can conduct electricity, but not as well as metals.

Front

What is an example of a metalloid?

Back

Silicon is an example of a metalloid.
