Properties and Bonding of Metals

What is a characteristic property of metals?

• Poor conductors of heat

• Good conductors of heat

• Made of plastic

• Not used in everyday objects

What makes metals good conductors of electricity?

• Their malleability

• Their high melting points

• The presence of free-floating electrons

• Their ability to be stretched into wires

What does it mean for a metal to be malleable?

• It can be stretched into wires.

• It has a high melting point.

• It can be molded into different shapes.

• It conducts electricity well.

What is metallic bonding?

• The sharing of electrons between two non-metal atoms.

• The electrostatic attraction between metal ions and free-floating electrons.

• The transfer of electrons from a metal to a non-metal.

• The attraction between positive and negative ions in a regular pattern.

Why do metals typically have high melting and boiling points?

• They are good conductors of electricity.

• A lot of heat energy is needed to overcome the strong electrostatic attraction in their structure.

• They are malleable and ductile.

• Their lattice structure is easily broken.
