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.
