Unlike non-metals, most metals tend to —

• conduct electricity and heat well.
• be gases at room temperature.
• break easily when hammered.
• have less luster and shine.

The ability of a material to be shaped in all directions without cracking or breaking.

• Hardness

• Ductility

• Malleability

• Conductivity
