Properties of Elements

Front

Metal

Back

An element that is shiny, conducts heat and electricity well, and is malleable. Example: Iron in farm tools like plows.

Front

Nonmetal

Back

An element that is dull, does not conduct heat or electricity well, and is often brittle or gaseous. Example: Oxygen in the air.

Front

Metalloid

Back

An element with properties of both metals and nonmetals, often used in electronics. Example: Silicon in computer chips.

Front

Luster

Back

The shininess or reflective quality of an element’s surface. Example: The shiny surface of aluminum foil.

Front

Conductivity

Back

The ability of an element to carry heat or electricity. Example: Copper wires in farm equipment.

Front

Malleability

Back

The ability of an element to be hammered or shaped without breaking. Example: Aluminum in cans.

Front

Brittle

Back

A property where elements break or shatter easily when force is applied. Example: Sulfur in soil fertilizers.

Front

Ductility

Back

The ability of an element to be drawn into thin wires. Example: Copper used in electrical wiring.

Front

Semiconductor

Back

A material that conducts electricity under certain conditions, used in technology. Example: Silicon in circuits.

Front

Example of a Metal

Back

Iron in farm tools like plows is a metal because it’s strong and conducts heat.
