Metal, Metalloid, or Nonmetal

Front

What is a metal?

Back

A metal is a type of element that is typically shiny, malleable, ductile, and a good conductor of heat and electricity. Examples include iron, copper, and gold.

Front

What is a nonmetal?

Back

A nonmetal is a type of element that is generally not shiny, brittle, and a poor conductor of heat and electricity. Examples include oxygen, sulfur, and carbon.

Front

What is a metalloid?

Back

A metalloid is an element that has properties of both metals and nonmetals. They are semiconductors and are used in electronics. Examples include silicon and arsenic.

Front

What are the physical properties of metals?

Back

Metals are usually solid at room temperature (except mercury), have high melting points, are good conductors of heat and electricity, and are malleable and ductile.

Front

What are the physical properties of nonmetals?

Back

Nonmetals can be gases, liquids, or solids at room temperature, have lower melting points than metals, and are poor conductors of heat and electricity.

Front

What are the physical properties of metalloids?

Back

Metalloids have a mix of properties from both metals and nonmetals. They are often semiconductors and can be shiny or dull.

Front

How do metals react with acids?

Back

Metals typically react with acids to produce hydrogen gas and a salt. For example, zinc reacts with hydrochloric acid to produce zinc chloride and hydrogen.

Front

How do nonmetals react with metals?

Back

Nonmetals can react with metals to form ionic compounds. For example, chlorine reacts with sodium to form sodium chloride (table salt).

Front

What is an example of a metal and its use?

Back

Iron is a metal used in construction and manufacturing due to its strength and durability.

What is an example of a nonmetal and its use?

Back

Oxygen is a nonmetal essential for respiration in living organisms and is used in combustion.
