Classify Elements as Metals, Nonmetals, or Metalloids

Front

What is a metal?

Back

A metal is a shiny substance that is a good conductor of heat and electricity, malleable, and ductile.

Front

What is a nonmetal?

Back

A nonmetal is a substance that is usually dull, poor conductor of heat and electricity, and brittle.

Front

What is a metalloid?

Back

A metalloid is an element that has properties of both metals and nonmetals, often semi-conductive.

Front

What property do metals typically have?

Back

Metals typically have luster (shine), are malleable, ductile, and good conductors of heat and electricity.

Front

What property do nonmetals typically have?

Back

Nonmetals are usually dull, brittle, and poor conductors of heat and electricity.

Front

What is luster?

Back

Luster is the shine or reflective quality of a surface, commonly found in metals and some metalloids.

Front

Can metalloids conduct electricity?

Back

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

Front

What does it mean for a metal to be malleable?

Back

Malleable means that a metal can be hammered or pressed into different shapes without breaking.

Front

What does it mean for a metal to be ductile?

Back

Ductile means that a metal can be stretched into a wire without breaking.

Front

Give an example of a metal.

Back

Iron (Fe) is an example of a metal.
