Front

Define a Metal in terms of its properties.

Back

Metals are good conductors of heat and electricity, malleable, ductile, and have a shiny appearance.

Front

Define a Nonmetal in terms of its properties.

Back

Nonmetals are poor conductors of heat and electricity, not malleable or ductile, and can be gases, liquids, or brittle solids.

Front

What is a Metalloid?

Back

Metalloids have properties of both metals and nonmetals and are semiconductors.

Front

What is the significance of valence electrons in determining an element's chemical properties?

Back

Valence electrons determine how an element reacts chemically with other elements.

Front

How does the conductivity of Nonmetals compare to that of Metals?

Back

Nonmetals have lower conductivity than Metals.
