What are metals?

Back

Elements that are good conductors of electric current and heat; tend to be shiny and bendable.

Front

List the three main groups of elements from least conductivity to greatest conductivity.

Back

Nonmetals, Metalloids, Metals.

Front

What physical properties are used to classify elements as metals, non-metals, or metalloids?

Back

Luster, conductivity, malleability.

Front

What type of element is Iron?

Back

Metal; it is a good conductor, malleable, and magnetic.

Front

What type of element is Silicon?

Back

Metalloid; it is a semiconductor and has properties of both metals and nonmetals.

Front

Define conductivity in the context of materials.

Back

The ability of a material to conduct electric current or heat.

Front

What is malleability?

Back

The ability of a material to be hammered or pressed into shape without breaking.

Front

What is luster?

Back

The way a surface reflects light; metals typically have a shiny luster.

Front

What are nonmetals?

Back

Elements that are poor conductors of heat and electricity; they are often dull and brittle.

Front

What are metalloids?

Back

Elements that have properties of both metals and nonmetals; they are semiconductors.
