Metals & Non-Metals Metals: Good conductors of heat and electricity. Have shining luster. Malleable (this means that they can be hammered or distorted). Ductile (this means that they can be drawn into wires). Most have high melting and boiling points. Are sonorous (give out sound when beaten). Usually solid at room temperature. An exception to this is mercury‚ which is liquid in nature. Examples: Aluminum‚ Gold‚ Copper‚ Silver‚ Sodium‚ Potassium‚ Mercury. Corrode or oxidize in
