Metals Nonmetals Metalloids

What is a metal?

• typically solid, shiny, malleable, and good conductors of heat and electricity.

• have properties of both metal and nonmetals; sometimes referred to as semiconductors

• Elements typically not shiny, usually a gas or brittle solid, not malleable, and poor conductors of heat and electricity.

What is a nonmetal?

• they are typically solid, shiny, malleable, and good conductors of heat and electricity.

• typically not shiny, usually a gas or brittle solid, not malleable, and poor conductors of heat and electricity.

• have properties of both metal and nonmetals; sometimes referred to as semiconductors

What is a metalloid?

• have properties of both metal and nonmetals; sometimes referred to as semiconductors

• typically not shiny, usually a gas or brittle solid, not malleable, and poor conductors of heat and electricity.

• typically not shiny, usually a gas or brittle solid, not malleable, and poor conductors of heat and electricity.

How do the physical properties of metals, nonmetals, and metalloids compare?

• They look all the same so there is no way to distinguish the difference.

• The physical property of an element allows you to identify based on what can be visually seen such as being shiny and/or dull.
